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, 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.

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.
Pacers
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.
Crew
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
Supporters are welcome anywhere out on course, with the exception of Hale Lane Aid Station. Please note that nothing must be handed to or received from runners out on course or in the field, which is deemed as crewing.
Medical
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.
Kit
99% of the course is on trail, therefore, trail shoes are advised, particularly given the time of year. There are sections of trail which can become very muddy in wet conditions. The course takes a number of steep ascents and descents, many of which will become hard going in wet conditions, particularly as the race progresses. These sections must be negotiated carefully in both the dry and the wet. Given the time of year, the threat of exposure is very real. Runners must carry the following mandatory equipment at all times.
There are many options regarding kits 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.
