Jurassic Coast Running Events

The Jurassic Extinction and Jurassic Coast event series takes place along the World Heritage site of the Jurassic Coast. This coastline spans from Old Harry Rocks near Studland to Orcombe Point at Exmouth, covering approximately 185 million years of geological history. All event distances conclude at the Exmouth Seafront.

Participants can choose from five different course distances, each traversing various sections of the coastal path:

  • 105 miles: Starts at South Haven Point (Poole) and finishes at Exmouth.
  • 100 km: Starts at Nothe Fort (Weymouth) and finishes at Exmouth.
  • 70 km: Starts at South Haven Point (Poole) and finishes at Weymouth.
  • 50 km: Starts at Lyme Regis and finishes at Exmouth.
  • 33 km: Starts at Beer and finishes at Exmouth.

The courses follow the natural terrain of the coastline. Each distance has a designated time limit for completion, ranging from 12 hours for the 33 km challenge to 38 hours for the 105 mile ultra. Several of the distances are recognized by ITRA/UTMB and offer qualifying points for participants. The event is scheduled to take place over a weekend in June, with varying start locations depending on the chosen distance. Visit the organization's website for the most recent information.
