We ran a full route of the Jurassic Extinction Ultra. This is a 120 mile single stage race from South Haven Point to the mouth of the River Exe in Exmouth. The route follows the South West Coast Path and includes the entire length of the Jurassic Coast World Heritage Site.

We had support at 15-20 mile intervals for food and water top ups but carried everything we needed in between.
