Wendover Woods 50 2026

Five loops of forest trail in Wendover Woods

The Wendover Woods 50 is a 50 mile trail race run in loops through Wendover Woods, near Aylesbury in England.

The Wendover Woods 50 is a trail ultra organised by Centurion Running and held entirely within Wendover Woods near Aylesbury, woodland operated by Forestry England. The 2026 edition takes place on 14 November and is the fourth and final event in the 50 Mile Grand Slam. The organiser lists 250 starters, a marked course, medical support and 9 aid stations.

The route is made up of 5 loops of 10 miles on forest trails and tracks. Centurion describes wide, soft trails with smooth descents and runnable climbs, set against much steeper ascents and descents scattered through each loop. The course has 10,000 feet of climb and is 99% trail, and some sections become very muddy when wet.

There is one distance, 50 miles or 81 km, with a 15 hour time limit and further cut offs along the way. The start is at 09:30 in the woods, a short walk from Trig Point Field on Aston Hill, where registration and the finish are based. The field is also the aid station at the end of every loop, so people waiting there see the participants pass 4 times before they finish. Supporters are welcome out on course except at Hale Lane aid station, but crew and pacers are not allowed and nothing may be handed to anyone in the race.

Anyone taking part can choose to share their own live position on Livebib from their phone, so friends and family can follow each loop from home. This is not the organiser's timing, and official results come from Centurion Running.
