Jurassic Extinction / Jurassic Coast 100

This event offers multiple distance options along the Jurassic Coast World Heritage site, which spans from Old Harry Rocks near Studland to Orcombe Point at Exmouth. Routes run along sections of the South West Coast Path and follow the coastal trail between towns on the Dorset and Devon coast.

Distances offered include:

  • 33 km Beer to Exmouth, 1050 m height gain
  • 50 km Lyme Regis to Exmouth, 1730 m height gain
  • 70 km South Haven Point (Poole) to Nothe Fort, 2200 m gain
  • 100 km Nothe Fort to Exmouth, 2900 m height gain
  • 105 miles South Haven Point (Poole) to Exmouth, 5100 m gain

Courses require self navigation on the South West Coast Path. Each distance has a published maximum time and minimum pace requirement. The event uses live GPS tracking and offers staffed, well stocked aid stations along the route. For finishers there are commemorative items: solid oak coasters for the 33 km, 50 km, 70 km and 100 km finishers, and a special buckle for 105 mile finishers. ITRA and UTMB index points apply to the 50 km, 70 km, 100 km and 105 mile distances as listed by the organiser.

Two organised recce days are planned to cover parts of the night section relevant to the longest races; each recce is roughly 20 miles and includes transport and support. Visit the organization's website for the most recent information.
