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

The Spring Trail Series offers three race distances: 75km, 50km and 25km.
