The Spring Trail Series by Ultra X takes place on the Serpent Trail, a stunning route that weaves through the greensand hills, river, woodland, and lowland heath of the South Downs National Park, a habitat that is rarer than rainforest and home to a variety of rare and endangered species.

The Spring Trail Series offers three race distances: 100km, 50km and half marathon.

As is always the case with Ultra X events, these are far more than just races, they are awesome experiences. At the start/finish, there will be an expo selling merchandise, hot drinks, food and much more. You are actively encouraged to stay on after your race and enjoy the festivities, BBQ and bar.

The address for the start/finish is the same for all four race distances: Haslemere Recreation Association (GU27 3AR) or what3words location bleaching.dive.unwanted. The start is a 10-minute walk from Haslemere train station and there is also parking readily available in the town centre.

All races are held under a full UK Athletics Permit granted through the TRA.
