Race Overview

At the 2026 Spring Trail Series we will welcome over 1200 runners and walkers to the Serpent Trail, a stunning route that weaves through the greensand hills, rivers, woodland, and lowland heath of the South Downs National Park.

To find the start, simply put ‘Cowdray Farm Shop, Midhurst’ into maps and you’ll be directed to the event parking by Ultra X high viz crew.

We designed the event to be the most accessible in the UK. All races start and finish at the same location, just outside the wonderful Cowdray Farm Shop (perfect for spectators). Furthermore, you can park your car at the start/finish village.

The Spring Trail Series offers five event distances: 12km, 25km, 50km, 50 miler, 110km.

START TIMES

110km start: 0500

50 miler start: 0700

50km start: 0900

25km and 12km start: 1100

Please arrive 45 minutes before your start time in order to collect your bib. If you’d prefer to receive yours in the post, you can select this option at registration.

At the start/finish there will be an expo selling merchandise, hot drinks, food and much more.

Should you choose, runners and walkers will be able to purchase camping at the event village for the Friday and Saturday night. You can book your pitch when registering for the event.
