Serpent Trail

Serpent Trail is a long-distance trail-running festival set in the South Downs National Park, centered at Petersfield Rugby Club in Hampshire. Runners can choose from five distances—100km, 75km, 50km, 20km and 10km—with the 100km route offering about 1785m of ascent, nine checkpoints and an 18-hour time limit. The largely signed course winds through rare habitats such as lowland heath and ancient woodlands.

Special features include coach transport to the race start, on-site camping, a Friday kids’ race, and on-site food and a licensed bar; walkers are welcome. The event takes place on Saturday 4 July 2026. Visit the organization's website for the most recent information.
