Join us for the legendary Arc 100

Arc 100 is a unique point-to-point race along the most exposed sections of the Cornwall Coast Path in England's South West. From Coverack to Porthtowan, runners will experience the stunning and dramatic 'arc' of Cornwall.

Arc 100 has a strict 36 hour time limit with additional checkpoint and safety cut-offs on route. With large stretches of coastline between aid stations, runners need the ability to be self-sufficient for long periods of time.
