The Serpent Trail Races 

The Serpent Trail is a long distance route within the South Downs National Park, from Haslemere to Petersfield that goes through heathland habitats rarer than rainforest!

The races we have created are a special journey through the greensand hills, lowland heath, woodland and river meanders of Surrey, Sussex and Hampshire!  

The 100k race is the full length of the Serpent Trail and has been designed to allow participants to be as fast and light as possible with regular checkpoints, a revolutionary kit list approach, pacers and support crews.  Starting on a Surrey high street, within a mile the trail enters woodland, ascends to the highest point in the South Downs National Park and snakes through glades, copses, fields and heathland as it rises and falls through the Wealden Greensand Hills.  

The 50k race starts from near Petworth, the mid-point of the Serpent Trail and along with the Half Marathon and 10k races is along the southern section of the trail to Petersfield.  The second half of the Serpent Trail has smaller hills and lower level sandy trails and paths with sections of road linking them up, so are suitable and inclusive for walkers as well as runners.

Each race has coach transport included from the Venue / Finish to the respective start of the race.
