The WW50 is a 50 mile foot race consisting of 5 x 10 mile loops on forest trails, entirely within Wendover Woods. The course mixes some of the most enjoyable trail running to be found anywhere, with wide, soft trails including smooth descents and runnable climbs. These sections are contrasted with some much steeper ascents and descents scattered throughout the loop. Runners will work hard for a finish at this race which will also act as the fourth and final event in the 50 Mile Grand Slam.

As with all Centurion events, runners will be fully supported by 9 well stocked aid stations, full medical support and a marked course. Race held under full UK Athletics Permit granted through the TRA (Permit Number TBC).

Aid Stations

The start/ finish location also acts as the aid station at the start/ end of each loop. Runners will make 4 visits there before finishing at the end of their 5th loop. The Hale Lane Aid Station falls at mile 5.5 of each lap and will therefore also be visited 5 times. A full list of the distances at which the aid stations fall and the respective cut off times, can be found here. Both aid stations will carry as a minimum: Tailwind, water, coke, chocolate, sweets, sandwiches, nuts, lots of fruit, Gu gels, wraps, sandwiches and other sweet and savory snacks. Hot drinks will also be available throughout the race at both aid stations. 

Drop Bags/ Finish Line Bags (the same singular bag)

Your Drop/ Finish Line Bag may be deposited at registration, whereupon they will be stored in number order in a separate tent and accessible to runners at the end of each 10 mile loop. Bags should be clearly labelled with runners name and bib number. Drop bags must NOT exceed 50 litres in size.

Course Markings

The course will be marked with our recycled Tyvek pink ribbons and pink Centurion marker arrows. There are a handful of road crossings/ to negotiate. These will NOT all be marshalled. 


No pacers are permitted at any point on the route. A pacer is an individual not in the event, who accompanies you on foot for any period of time. 


No crew are permitted at any point on the route. This means no-one except our marshals can hand you anything and you can not give anything to anyone else except our marshals.


Supporters are welcome anywhere out on course, with the exception of Hale Lane Aid Station. Please note, nothing must be handed to or received from runners out on course or in the field, that is deemed as crewing.


There will be a dedicated team of race medics available throughout the race including a static first aid team at the start/ finish check point and a roving team within the Woods. If you suffer an injury or accident that warrants direct medical attention, the medics will be on hand to provide you with exactly that. Contact numbers and full details of what to do in an emergency will be given to you in the pre race information packs and again at race registration. Due to the nature of the course ie. some remote and far from roads, the medics may take some time to reach you, or potentially be out of contact tending to other runners. In those instances you should contact the emergency services on 999 AS WELL AS the race medics. Full instructions on what to do in an emergency can be found in the infopacks


99% of the course is on trail, therefore trail shoes are advised. There are sections of trail which can become very muddy in wet conditions. The South Downs are formed of chalk and are composed of significant sections of exposed and slippery chalk bed and rocks. These sections must be negotiated carefully in both the dry and the wet. The ridge is very exposed and in wind and rain runners can become cold quickly. Visibility can also be extremely poor under cloud cover. It is essential to carry the items below in lieu of these potential outcomes. There will be kit checks prior to the race as well as potientially during and at the finish. Runners must carry the following mandatory equipment at all times. A time penalty of one hour will be imposed for any item found to be missing at any point on course. Please refer to this page for explanations on the inclusion of the below items. 

There are many options regards kit for fulfilling these requirements and those of other events. We stock what we believe to be the best options at our online store available by clicking here. Please ask us if you have any questions.
