Jurassic Coast 100

The Jurassic Coast 100km starts from Nothe Fort in Weymouth. We’ve loved using this venue for the last few years. It gives this race the start it truly deserves. We can’t wait to get back there in June!

It’s a 9pm start on the shortest night of the year. Highlights include reaching Golden Cap in time for sunrise. It’s the highest point on the South Coast of England and well worth the effort for the views from the top! 😍

The 100km has a time limit of 25hrs and it’s open to both runners and walkers. For anyone who finds the idea of running/walking overnight a little daunting, we offer the opportunity for you to be accompanied by a friend between 9pm and 7am.

See you here on the 20th June! 🙌🏻
