All courses follow trail terrain with a small amount of road. Surface types include grass trails, farm tracks, woodland and chalk paths.

The 100-mile, 55-mile and 50 km races all have marked routes and live GPS tracking with chip timing.

Aid station provision differs by distance: the 100-mile has 12 stations, the 55-mile has 8 stations and the 50 km has 4 stations.
