What you’re in for

A February trail race that opens the Classic Element Trail Series. All three distances (16 miles, marathon and 50km) start and finish at Queen Elizabeth Country Park and climb Butser Hill, the highest point of the South Downs, twice. In between, the routes loop over the rolling downland and muddy tracks of the Meon Valley. The course is fully marked, with aid points listed by mileage. You must carry at least 500ml of fluid, and BigFeat recommend loading the GPX. The marathon and 50km start at 8:30 and the 16 mile at 9:00. Cut-offs are 5, 7.5 and 8.5 hours. Canicross is not accepted.
