What is It 

Centurion Running One Up is a virtual event which takes place over 7 days, starting at 0001 BST on Monday 17th February 2025 and ending at midnight BST on Sunday 23rd February 2025. The event is for everybody, anywhere in the world, of any age. 

Unlike the One Slam challenge, entrants do not have to specify a target before hand. There are levels to achieve and once you've reached one you are welcome to go on and shoot for the next, all the way to the top!

You have a week to aim for the following targets. Elevation can be gained by climbing, running or walking anywhere including outside on road, trail or mountain, inside on the treadmill, on the stairs etc. But when you register, you must select whether you are entering the 'Standard' division or the 'Up Only' division. Classification as follows:

Standard: Where all of a runners activities involve ascent and descent eg. out on the trails, mountain or road where lifts from cars or gondalas or use of bikes are not employed to descend.

Up Only: Where any of the weeks activities involve ascent only eg treadmill, stair climber or any activity involves assisted descent eg lifts, cars etc.

If any one of your activities falls into the up only category then you must enter that category.

The levels to aim for are as follows - gain will be calculated and submitted in feet but for reference, the height in metres is also shown below:

• Level 1: Box Hill - 735 Feet (224m)
• Level 2: Kinder Scout - 2087 Feet (636m)
• Level 3: Ben Nevis - 4413 Feet (1345m)
• Level 4: British Three Peaks - 10,052 Feet (3064m)
• Level 5: Mont Blanc - 15,780 Feet (4810m)
• Level 6: Everest - 29,030 Feet (8848m)
• Level 7: Rum Doodle - 40,000.5 Feet (12192m)
• Level 8: Olympus Mons - 69,648 Feet (21229m)

To submit your result, simply enter the amount of elevation gain you achieved over the course of the week either during the week if you finish early, or at the end of the week. Your award will be sent out to you once the event is finished.

The results will be set out by level achieved.

You must submit your results via the link above before noon BST on Monday 24th February 2025.

Beyond the results this is all about community engagement which was an amazing and overwhelming aspect of the one community event. We want you to share your runs/ hikes and journeys to your own finish line via any and all channels. You can tag us on facebook, twitter or instagram under the hashtag #centurioncommunity. Photos are strongly encouraged! We will share what we can and award spot prizes to the best uploads and engagements over the course of the week.

How to Register 

You can register by clicking on the button linked at the top of this page. Registrations are open until the final minutes of the last day!

All 2025 One Slam entrants receive free entry to One Up as part of their entry fee. A link to register will be sent out via email to all One Slam entrants prior to the start of the One Up event. It is completely optional to add this event on to the One Slam event.

During registration you are able to register for just you, or an extended group of family or friends as you wish.

The event is open to everybody no matter your location. We hope to see many international runners taking part. 

You can also register for the canicross event - Simply select 'yes' during registration to 'running with a dog?' and you will appear in your age group but also the canicross category.

When you sign up you will need to include a shipping address. We will then post out your medal or buckle to you within a fortnight of the end of the event. 

How do I upload my results

Simply head to the submit results button at the top of the page or by clicking here and add your details, together with the amount of climb you achieved. You may submit more than once if you wish and it will superseed your last entry.

You can run anywhere, anytime. Outside on road, trail, on the treadmill, round your garden, anywhere you like. But please only count sessions where you have actively gone out to add to your distance, not simply steps around the house or as part of your normal day to day movement.

This is an honour based system. If you have a GPX file, link to strava or other training platform then we will ask you to enter that alongside your manual time entry. To be eligible for awards (winners of each distance and each category) you need to upload files as proof of your run(s). However if you don't have access to a watch, phone or other recording device or prefer not to use them - no proof is required to be eligible as a finisher, just enter your times manually.
