Spine Race Kit 2024-2025

KIT AND LOGISTICS

This area of the post is specifically designed to look at the detail of all aspects of the kit, footwear, apparel, nutrition and miscellaneous items that you need to think about in order to compete safely and successfully in the Spine Races or indeed, for winter in the mountains.

This video accompanies this post, going into further detail on all of the items below as well as the drop bag and how to think about packing for the race.

Clearly a huge caveat needs to be placed at this juncture. Every single person emerging from the Spine will have a different view on kit, how in functions, what minimum requirements are vs what you actually need to carry.

You need to think very carefully about what you need to carry/ have access to and not just what's on the mandatory kit list. The kit list is there as a safety net and often just in case of emergency. What you actually require to stay safe and perform well at the Spine Race goes far beyond it.

We also need to be realistic about cost and what you do and don't need to buy. Some of the kit is very expensive plus there is of course a large energy cost to production and transport in a lot of cases. So consider what you have already that is fit for purpose, what can be borrowed and what can be hired. As time goes on and we are able to put the time and resource into it, hiring kit is something we'd like to get into - many already do this. The facebook group here is a valuable resource in borrowing kit or getting advice on how to look after it.

Cheaper alternatives are available for everything, always look at the compromise though: Weight vs Packability vs Price. We've picked out the best balance of those three things, in our opinion.

And on that note - as a retailer of ultrarunning gear, all that happened as we went sourcing the best kit, was that we started to stock it. So that we could pass on a collection of kit that was all in one place for runners interested in the race - with first hand, real world advice. We don't stock it all but we're getting there. All of the links take you to the best place to find each product. It might seem salesy but believe me when I say I think the biggest saving is actually hopefully on people's time trying to find good advice and being able to ask questions about kit/ shop from us at the same time. We're here for the detail.

However, we are not the authority on Spine Race kit. If you have any questions or want to check if what you have meets kit requirements for the race, then you should contact the Spine Race and Lindley Chambers who heads up their kit side of things, via his email [email protected] . You can also read his advice and tips on kit and kit check on this page here.

What I've done here is distilled down my experience not just at the Spine but of a nearly two decades of racing in all conditions, utilising a wide range of winter kit over and over again - as well as organising more 100(+) mile ultra distance events than anyone else in the country! I know there will be some people who have no idea of who I am so I have included a short bio at the end of this post.

This kit has been used, not actually mainly in racing but in training and on days out on the hill, in winter. You must get used to using the kit, particularly working out what footwear and what layering systems work for you. I am around 65kg, 5ft7 and without tooting my own horn, tend to move towards the mid to the front of the pack in events. I would say days out over the Wainwrights in winter were a turning point for me. Learning to read the forecast, particularly with regards to wind speeds at height, anticipate clothing requirements, navigate in the dark and mist with map and compass and scramble/ climb very difficult ground - these are the skills that make me feel most comfortable in terrible weather. A lot of my racing might also seem irrelevant but you draw on the experience of everything that has gone before, in events like the Spine. Races/ Rounds I've run that help contribute to choices here include Tor Des Geants, Arc of Attrition, Lakeland 100, Western States, Bob Graham, Paddy Buckley, Charlie Ramsay, Leadville, Lakeland, 4Deserts Series (antarctica being the most cold weather specific). But more so things like the Wainwrights in winter, crossing Iceland on foot and many long days out by myself. 

Finally you will find kit suggestions and comments throughout this text which features my own kit. Firstly from two of our team runners - Debbie Martin-Consani who has finished the race twice including a win at the 2022 edition. And Edwina Sutton who finished third in the 2023 race. Finally, from 2023 Mens winner Damian Hall.

A link to the full mandatory kit list for 2024 (and 2025) is available here. All of the below kit meets the criteria for the event. 

Footwear:

Clearly, managing your feet is one of the handful of major things to concentrate your energy on. For some time as a team we had been waiting on the La Sportiva Cyklon Cross GTX to come out. We'd sat in a team meeting back in April and Jono Wyatt had pulled a pair out and previous race winner and PW Record Holder - John Kelly - sitting to my right, had asked on the spot if he could possibly just take them home with him. They are effectively an insulated, waterproof, lightweight shoe - that looks like a boot due to the gaiter. The sole unit is La Spo's grippiest rubber. The upper is soft, warm and you can dial it in tight or back it off using the boa system. Then there is a Gore Tex gaiter coming up to ankle height, so effectively there are two waterproof layers to the shoe. This kind of shoe has moved the game on with regards to protection from winter/ very wet or cold conditions. It feels like you are wearing a lightweight shoe, whilst getting the protection of a mountain boot (not crampon compatible as the sole is not rigid enough - great with microspikes of course). Others were still wearing regular trail shoes and asking more of their socks but for me whether you are running up the front or scraping cut offs, this shoe does it all. The other model I had in my armoury was the La Sportiva Blizzard. This is again a Gore-Tex shoe with a debris gaiter, and has a metal stud matrix built into the sole unit - essentially built in nano-spikes so you can run across ice without issue (note these will not pass kit check, you still need a separate set of spikes or yaktrax).

The other component of course, is socks. I hadn't worn waterproof socks since the Last Desert Antarctica in 2008. But I got hold of some Dexshell Compression mudder socks and quite frankly they became the most important piece of kit I had. They are impermeable to both water, but also to debris. And at knee height you have to be in a very significant bog or river to get water in the top. If that does happen, they then insulate that water like a wetsuit, and keep your feet warm. 

I had no liner sock, just the Dexshell. I started in the Cyklon Cross. Because it was minus 2-3 in the valleys and 6-7 on the tops all week, every hard surface was covered in ice so I then used the Blizzards for Day 2 and 3. Before going back to the Cyklon Cross for the last two sections. 

All four of the runners mentioned on this post including myself, Debbie, Eddie and Damian all used the same DexShell sock for this race. 

2022 Womens race champion Debbie Martin-Consani used a liner sock in combination with the DexShell and had just as much success with her feet - Debbie talked about her foot route in a post-race intstagram post here. Liner socks should be thin, it is well worth experimenting with both options in your training. Damian Hall comments: 'I too use DexShells and tend to wear a toesock as a liner. The only problem I've had is from feet being too warm in conditions less severe'. Again, test them in training.

With the Dexshell Sock, and then the Cyklon Cross/ Blizzard I had zero blisters (i had one small bit of skin come off at the finish because i tore off a bit of preventative tape too soon with wet skin underneath), zero hot spots, never once got cold feet and always had the grip I needed. I took my shoes and socks off in at the 144 mile check point and the medic asked me where I'd washed my feet - they stayed that clean and clear. The Blizzards - after 40 or so hours began to make my feet tender, I think where the sole is more rigid and the spikes less forgivining but they were priceless for the icy rocks, hence the switch back to the Cyklon Cross. I take half a size up in both to allow space for the thicker Dexshell Sock. 

So as an N of 1 sure, but if you want to get through the Spine without foot issues, there's a good system to try. This is more of an invidivual area than almost any other part of your race strategy, besides nutrition.

Separate Spikes or Yaktrax are part of mandatory kit. Nanospikes won't pass kit check. I would always carry a Yaktrax for speed and weight, but also have my Kahtoola Microspikes in the drop bag. These are essentials for any winter mountain day anyway, will see plenty of use! I've had my Yaktrax since 2008, still going strong.

Lower Body:

All through training including in sub zero temperatures for many hours, I'd worn one pair of tights and lightweight waterproof trousers. But in the race this was simply not enough. I ended up putting on a second pair of tights and then a waterproof trouser. I needed two pairs of tights to stay warm enough at the coldest times. Remembering then that these stayed largely dry through the race, I didn't touch my spare/ third pair but you need to carry one additional pair to that which you are wearing. I can't see getting away with less than three pairs of tights is viable, and a fourth would be wise.

As for the trousers, the Drizzle Pant (unisex) is a light, tapered running waterproof trouser, you feel like you can move fast in them. This was good for almost everything, you could put on a heavier Gore-Tex weight trouser in wetter weather however, that could be a valuable addition.

On the lower half, Damian Hall, moving on the whole much faster (than almost anyone else!) found that one pair of tights was often enough, with a pair of lightweight waterproof trousers over the top just for the very worst sections. But certainly for us slower movers a bit more protection is worth getting used to in training.

Upper Body:

This is a huge area, clearly. A good mountain layering system and an understanding of that is worth looking at. I know some runners will simply stick a Buffalo Jacket on and that'll cover almost anything they need. But I prefer the layering because it allows flexibility around conditions.

You should look at having a base layer. Two mid-layers - ideally a breathable fleece type material and a heavier weight fleece jacket, a primaloft jacket and two outer shells - a windproof and a waterproof.

For the majority of the Spine I had on six layers. Base Layer - La Sportiva Jubilee. Mid-weight fleece - the OMM Core Jacket which is super light, breathable and packs suprisingly small. A La Sportiva zip up fleece hoodie / Montane Protium Hooded Fleece. My La Sportiva Primaloft jacket. My Blizzard Windproof. A Montane Gore-Tex Active outer shell which I had on in the wet/ snow showers only. In training, I never had more than three layers on. But thermo-regulation goes out of the window several days in and you need to anticipate wearing far more than you ever will in preparation.

You then also need to have back ups for these layers. They will get wet at some stage. Having spares in your pack and your drop bag, is essential. Here's how and why.

Before a base layer for us men, Eddie Sutton adds 'this sports bra is thick (think free extra warmth) but has no seams and a large surface area to protect back. I had no chafing under arms or on back and it never felt wet so I didn’t get cold.'

A good base layer needs to be able to move moisture away from your body whilst insulating to a high degree here. The truth is at the Spine you are only really sweating up on climbs and even then if you are, you need to look at your effort level. I had several, one on me, one in the bag (that is the mandatory kit rule - one spare base layer not in use) and then a couple in the drop bag. 

A good quality Waterproof Jacket is obviously crucial. Whilst a 10k/10k lightweight jacket will pass kit check, it's absolutely inappropriate to start this race with something that lightweight. The minimum level I'd suggest for the race is Gore-Tex Active. Right now we have the privielege of being able to wear a Gore level jacket which weighs close to nothing. The jacket I had for the majority of the race was the Montane Phase Nano. This is the evolution of the Spine Jacket. They are both Gore-Tex Active which translates to much greater protection than any of the other lightweight (10k - 20k range) jackets, durable, adjustable hood and hem and extremely lightweight. The womens edition of the Phase Nano is not out until September 2023. So the Spine jacket for both men and women and then the Phase Nano Mens from Spring and Womens from Autumn 2023 are the pick of the bunch for me. 

Eddie Sutton comments 'I had run in a montane spine jacket for a few years size 10 one…then about a month before the race I purchased a size 12 one which I wore for the race and was so pleased I did. It enabled me to wear more layers underneath, I had more mobility and it was easier to get the hood up and down. I then took the size 10 in my drop bag ready to double layer if I needed to but we had a dry year!'

Some will point to needing heavier jackets than this - Gore-Tex Pro, higher denier grade material will stand up longer to bad weather, but that is personal preference - again weight vs packability vs protection - I believe Gore-Tex Active in these latest Montane jackets is the way forward. 

You could certainly argue the case for needing one or two spare jackets too - if you are soaked through and keen to leave a check point in a hurry. 

I would put a good windproof up there as just as important as a waterproof. There were times during the race where the wind was up to 40mph and on a -6 temperature reduced wind chill to -15. That cuts straight through a waterproof because of the nature of the material, where a windproof offers substantially more warmth/ protection. It still amazes me how a garment I use almost every day is so neglected in the running world. The Blizzard and Briza are nnot much over 100 grams and provide that layer of protection.

Finally the Primaloft layer, go for primaloft and not down. Primaloft still works as an insulating layer when it wets out but down does not.

Headwear:

The main way you will regulate your temperature during the race is by removing or adding hat/ headwear and hoods. Far simpler and quicker than removing layers. The Core Beanie from OMM is breathable, so you don't get a sweaty head. It weighs next to nothing and is made out of primaloft active. 

Another good option is a headband which allows your head to release the heat whilst ensuring you don't get cold ears, which can be a real issue.

Hoods up or down in conjunction with how cold / windy it is - the hood on your windproof being the main one to use.

I also wore a Weather Resistant/ Waterproof Cap for the first day when it rained hardest, just to re-inforce the peaked hood on the waterproof jacket and ensure rain stayed off of my face. 

Take plenty of buffs. We all have them. Good for face covering, extra warmth/ neck cover, head cover and of course wiping stuff up!

Gloves

Understanding combinations of gloves based on how cold and wet your hands might get is obviously as important as any other facet of your kit. If you lose operation of your fingers, you can't eat, undo bottle caps, undo zips/ change clothing. Basically somewhere between inconvenient and dangerous. Getting into this situation was the defining factor for me in bailing off of a second Barkley loop in 2019! I got my kit wrong when the weather turned very quickly and couldnt' navigate or do my jacket up.

A liner glove, with fingers is worthwile and worth having several pairs of. I'd start with one on and one in your bag (mandatory kit). Then a couple more spares in your drop bags.

As a warm overmitt, always go for Primaloft over Down, because when they get wet - the primaloft will still work as an insulating layer. The Montane Prism Dryline is their warm Prism Mitt, super soft, comfortable and light, but with a pertex waterproof layer. I had three pairs. One on. A spare in my pack. One in my drop bag.

Then a waterproof outer glove for really harsh conditions - the Minimus overmitt also from Montane. Just one pair of those.

Pack/ Belt:

During the race I used 2 different packs. I started out with an old S/Lab Peak 20 which was a skimo pack from 2017 - basically an old faithful. Before I got hold of a Montane Gecko 20. It was a case of using what I was used to. I switched to the Gecko 20 at Middleton when the back zip failed on the Salomon and that must have been fate. Because the comfort level of the Gecko is incredible. For me it is the superior option and I wished I had started in it. The best features in my opinion are the adjustable straps across the front which allow cinching around unknown layers of clothing, and the comfortable waist belt that takes some of the load off of your shoulders. But particularly the soft elastane blended material and side pockets. Unlike almost any other pack you can reach straight into them, just down of your waist but close to the front, and stuff them full of almost anything you might need on the run. Honestly they are like Mary Poppins' bag. The fit is exceptional, so comfortable and despite the weight you barely notice you have it on. For me, there was always ample space in the back - I packed light but then added a complete set of spare clothing on the top for easy access and there was ample room. I also used a Naked Band for additional space early in the race, particularly useful for excess nutrition. 

Eddie sutton also used the same back and trained and raced exclusively with it. She comments 'it's a super comfortable pack, I didn’t feel the weight or pack rubbing (but I trained a lot with the pack too!) I brought an extra chest strap from montane and attached that high up which made a huge difference too.'

For further space, the OMM Chest Pod is compatible with almost any vest or pack, by adapating the fastenings that are provided with it - giving you front access to another 4 litres. I have never found I have needed this, but many in the race use this set up.

For greater capacity - if you are someone who plans to carry bulkier jackets, extra food, or less packable sleeping bags etc, then the best 30 litre option is the UD Fastpack 30, or FastpackHer 30. Again with the belt added for more space.

Lighting:

My go to lamp for the last 3-4 years now has been the Petzl Swift RL. Light, packable, easy to change rechargeable battery, long lasting and plenty of light and power. But. I found out during the first night that the lamp didn't like just how cold it was here. It's not been asked to do that duration in that cold before and because the battery was front mounted on my head, it was more exposed to that cold and seemed to drain quickly. That is anecdotal, lithium batteries should not drain any faster in that level of cold per se but that was my experience here. The batteries were all fully charged.

So I switched to my Petzl Nao RL which is Petzl's newest headlamp offering. On low reactive setting I got tons of light, more than I ever needed, and one fully charged battery lasted over 20 hours. I would only ever choose this lamp again. It's light, the battery is on the back which balances the weight out on your head, and crucially means it is protected from the bitter cold by your hood/ gets less cold. 

A rear Red LED is mandatory. Rather than a cheap one which will likely break, I attach a Petzl E+Lite which has the added bonus of being usable as a back up emergency lamp with several other settings.

Sleep System:  

Full disclosure here, I used this in training and on the freezing cold floor in Bellingham but I did not Bivi out during the race. The Thermarest Hyperion 32 has a comfort rating of 0 degrees C. It is super lightweight, but immensely comfortable and feels substantial despite how small it packs down. It is the minimum rating to pass kit check, but honestly with the Mat, Bivi and Clothing you have, it is unlikely that you will require more than this bag. We also stock the Hyperion 20 which is rated down to -6C for those who plan to bivi out or who want that extra layer of safety/ comfort. You can of course find other marginally lighter, extremely expensive alternatives but with performance vs packability vs weight, this is the optimum bag for me.

The sleep pad - I opted for the lightest as once again, I wasn't planning on a bivi unless in emergency - but I am happy having bivi'd on it before that whilst not the most comfortable night, as an insulating layer it does everything you need eg. gets you off of the freezing cold ground which is conducting your body heat away very quickly indeed. The Neo-Air Uberlite inflates extremely quickly and is a pass at kit check. Again it feels substantial. To me, the mat is the least important thing. If you try to inflate a mat like this with little or no shelter in high wind in an emergency you may as well be holding onto a kite. You need to get the bivi out first and try to inflate the mat inside of it whilst pinned down and ideally behind shelter. You need to practice these things in training!

With the bivi, I have again gone super lightweight, almost as light as you can go. The less durable bags eg SOL will fail at kit check. This is a waterproof bag with taped seams and perfectly adequate to keep you protected for short sleeps or awaiting assistance. This isn't a bag I'd hang out in year round for comfort - but that isn't why I am carrying it during this event.

Navigation: 

The Pennine Way is not a well marked trail. You will find finger posts and the acorn symbol in lots of places. But nothing it all in much greater amounts. Map and compass are mandatory kit and for good reason. If you'd had your watch die and/ or your OS App jumping all over the place in heavy clag on the high mountains, you need to be able to use them. Again for me it was a hard lesson on top of Red Pike by myself winter in serious conditions when the electronics all failed that forced me to take 'thumbing the map' more seriously. But, I would use the maps as a back up here because you ideally want hands free for poles, eating and gates. So use the excellent GPX trace, uploaded on your watch. It will tell you when you are going off course and when to make a turn. The Coros Vertix 2 has the longest battery life of any watch going, so we stock that to try to ensure least charging time. 

The handheld GPS you will see some using as a primary navigation device but more often than not it is a back-up. We used it on the Cam Road section on the longest stretch between check points, when my watch died. The Garmin 66S is easy to use even with big gloves on, takes 3 x AA batteries which are easily changed and is essentially bomb proof navigation. You need to learn to use the funcationality before you head out, you will need to upload the right maps for the Pennine Way - it doesn't come with these built in and you will be best off leaving it switched on, so if you do need to use it it is already there with the route and your position on it, not loading up in harsh conditions as you stand around waiting for it.

Reference a compass, I personally prefer a thumb / orienteering compass, but that won't pass kit check here so get a solid reliable compass like the Silva Ranger instead.

Poles:

I'm not sure if anyone went without poles but I'd be suprised. For stability, for measuring the depth of bogs - seriously, and for more efficient forward movement they have to be considered essential. Whilst I am a huge fan of Leki's Ultratrail FX.One Superlight poles which I used for TDG, I have always used a Black Diamond Carbon Z or FLZ pole when wearing gloves. They are super light, durable, fold down quickly and easily when out of use and most importantly have an easy to adjust hand strap so that I am not trying to squeeze the otherwise excellent Leki Shark Glove system over several layers of changing glove types. The FLZ have the added bonus of being height adjustable on the move.

Poles: Black Diamond Distance Z Poles

Stove/ Cooking / Eating System:

Aim for me is to be able to boil water quickly and simply but for it to be reliable. Whilst meths is lighter and more packable, the chance of a leak and the hassle of the longer burn time don't make it worth it for me. So I like gas options. Stoves are tiny these days and I use an Alpkit Kraku screwed straight into the gas canister, with storm proof matches to light. Remember you can't blow these out! So get used to letting them burn out in your hand like a sparkler! The Bugaboo mug from GSI is titanium so super light and useful obviously for drinks at the CPs - it is also good to use on the stove and boils extremely quickly, the 400ml limit you need to carry for kit - also coincidentally the amount you need for most rehydrated meals. I'd say good going less than 5 minutes to brew. The bugaboo will be HOT when you pick it up, but the handle is separated - so make sure you wear a glove and within a minute or two is fine to hold. Again, I wouldn't use this system day to day but on the spine (the bugaboo is not meant for this, it will eventually start to deform if you burn it for ages and ages) but it's everything I need here and more. The Titanium Spork from Optimus weighs nothing. 

For flasks/ water, it's worth carrying insulated soft flasks so that your fluid has less chance of freezing. My flasks froze several times leaving me an issue on those sections. It is also worth carrying a filter bottle which you can then decant, if you choose to or need to fill up from questionable sources.

Medical

Take a decent medical kit with you. Look at what is on the kit list, ensure you have it all but also think - what do I really need to carry? Pre-taping feet and having the right, quick to use tools to do that is something to look at pre-race. I am not a big fan of pre taping, but the conditions at the Spine are unique and by adding tape strategically you can often offset some of the worst problems. Remember, don't get into a check point and rip the tape off. Be careful. Your skin will be moist underneath and will tear more easily, so take extreme care when removing and replacing tape.

Other Mandatory Kit

Lifesystems Hurricane Whistle - far better than the one that came free with your pack. They will make you blow it at kit check!
Swiss Card Knife/ Scissors - This is an expensive option but essentially gives you lots of other useful kit for almost no weight/ size. The blade passes kit check in length. Cheaper replicas are available.
Bolle Safety Goggles - Light and cheap. Tinted expensive ski/ mountain goggles won't pass kit check, you need a clear goggle. These are worth getting used to in training as they need to be adjusted to feel comfortable. Lots of similar options in their range, must have a headband.
GSI Cathole 'Poo' Trowel and Tissues plus poo bags

Food and Drink

This is perhaps the most individual area of all. My advice to you is to consider carrying not just the 3000kcal minimum you are required to have, leaving each check point, but ensure what you have is going to be appealing and easy to consume over very long periods. 

In races in the past I have consumed exclusively gels - including at Western States in 2011 where I ate 70 Gu's. For this race I took almost no sports nutrition with the exception of some Maurten 320 CAF 100 drink mix primarily for the caffeine overnight. 

The other critical component is thinking about freeze dried meals. You won't need these at the check points which are very well stocked, but you will benefit from them at certain points in between. Either at the 0.5 check points or at the pop up locations with MRT where hot water is given. Or again, if you stop to brew up yourself.

I ate all of these things during the race and these options worked best for me. This is a very individual area however.

Non Mandatory but Borderline! 

Battery Packs: I used two larger power banks here in my drop bag, to charge batteries between check points. And then two smaller ones here that I carried on my person. Plug sockets whilst available at some check points are far from guaranteed. This system allowed me to charge everything for 5 days, with plenty of power to spare, without ever needing mains power. My watch, headlamp and phone cables, I carried in my bag to recharge on the go - I only needed to do that between Hebden and Hawes due to the length of that section. But it was nice to know I had that option if I needed. 
Lifesystems Ear Plugs - It's noisy in the bunk rooms!
Anti Chafe: Bodyglide
Dry Bags: The Ortlieb 13 litre dry bag fits nicely in the Montane Gecko 20 and is truly waterproof/ hard wearing. I then use lighter Exped Fold Lite Dry bags for other kit and my bags to go inside drop bag bags.
Repair Kit: OMM Waterproof Patches, Cable ties, Duct Tape, KT Tape, bungee. Shoe, pack, pole, clothing repairs are almost certainly going to be required at some stage.

BIO

My Spine Race finish in 2023 came 17 years almost to the day, fter my first ultra.

I began in 2005 and my first big adventure was the MDS. I went on to become the youngest finisher at the time of the 4Deserts Series including multi-stage races across the Gobi, Atacama, Sahara Deserts as well as on Antarctica. In 2009 I began running 100 milers and have finished quite a few of the bigger marquee events to date including:

Western States, Leadville, UTMB, Arc of Attrition, Lakeland, WHW Race, Caesars Camp, Old Dominion, Rocky Raccoon (x 5), Autumn 100 etc.

I've also explored the longer single stage races finishing Badwater, Spartathlon, GUCR, many 24hr races including 2 Silver medals in a GB vest and more recently the Tor Des Geants.

In 2011 I started Centurion Running and we've had a stable of 50 and 100 mile races since that time. I have personally Rd'd over 50 races of 100 miles or more and 30 x 50 milers in that time.

Outside of racing I ran the Bob Graham in 2014, the Paddy Buckley in 2021 and the Charlie Ramsay in 2022 made me the 73rd person to complete the Big 3 in under 24 hours.
