UK Ultra Winter on the Downs

The UK Ultra Winter of the Downs on 5 December 2026 includes a 100 mile, 55 mile and 50km race around the trails of East Sussex.

All distances are on single loop courses that start and finish in East Dean just outside the seaside town of Eastbourne. The views are spectacular, and the terrain is a combination of grass trails, farm tracks and woodland/chalk paths. They are generally very runnable with rolling hills with some longer, steeper climbs.

100 mile runners begin over the famous Seven Sisters before heading up towards Plumpton and out towards Findon along the South Downs Way. The route then loops back around towards Lewes before finishing back at the start.

55 mile runners also begin over the famous Seven Sisters before heading up towards Mount Harry, Blackcap and Lewes along the South Downs Way. The route then passes Mount Caburn, through Glynde and Firle before finishing back at the start.

50km runners will leave East Dean on a route that runs over the Seven Sisters and through the Friston Forest towards Firle, before looping back to the start.

All routes are marked with regular, well stocked aid stations.
