Notable Features

The race showcases the dramatic Jurassic Coast with its ancient geological formations and iconic landmarks like Old Harry Rocks and Corfe Castle. As part of the Classic Element Trail Series themed around water, the event emphasizes the coastal environment that has shaped this rugged landscape. The cupless event format reflects environmental consciousness, and runners can opt for tree planting instead of finisher medals through the Trees Not Tees program.
