On 4 July 2026, The Serpent Trail 2026 returns as a full trail-running festival on the long-distance Serpent Trail, with all races finishing at Petersfield Rugby Club in Hampshire. The headline 100k ultra traces the full length of the trail from Haslemere to Petersfield, while the new 75k option and the classic 50k ultra carve their way through lowland heath, ancient woodland, coppices and pretty villages on mostly soft, sandy paths with some short road links. Shorter 20k and 10k races start further south along the route (near Midhurst and Dumpford), giving runners a taste of the same scenery on a more compact scale. Across all distances, the terrain mixes rolling greensand ridges, heathland clearings, forest tracks and flowing singletrack, creating a route that’s hilly enough to be exciting but very runnable. With coach transport to the various starts, well-stocked checkpoints and fully marked courses, it’s a highly supported way to experience one of the South East’s most beautiful trail corridors.
