What Makes It Great

The Arc 25 is a 25-mile point-to-point trail race from the coastline near St Ives to the finish at Porthtowan, following the South West Coast Path through Godrevy beach, the sand dunes at Hayle Towans, and the dramatic cliffs above Portreath. With 1,240 metres of elevation and an 8-hour time limit, this is a genuine trail race in genuine winter conditions — no support crew allowed, mandatory kit required — making it an ideal gateway event for runners preparing for the longer Arc distances.
