Organised by Centurion Running, this 50-mile race consists of 10-mile trail loops in the Wendover Woods. The race starts and finishes in Halton, Aylesbury, and the route is marked with reflective tape, arrows and ground paint.
The route includes 9 aid stations with drinks and snacks (water, soft drinks, hot drinks, sweet and savoury snacks, fruit, gels and sandwiches) and medical support. The course is fully marked.
Race entry requires compliance with the organiser’s qualification standards which specifies runners should have completed a marathon distance event within cut-off times since a specified date which will vary each year. Mandatory kit checks will be carried out before, during and after the race.
The cut-off is 15 hours but partial cut-offs will be enforced at aid stations. No pacers are allowed and crews must provide assistance only at the designated areas.
