Arc of Attrition by UTMB
Arc of Attrition by UTMB is a coastal trail running event based in Perranporth, Cornwall, UK, held each January along the South West Coast Path. The route uses coastal and cliff paths and is exposed to winter weather; organisers describe rugged cliff paths, relentless climbs and unpredictable winter conditions.
The event programme includes four races with distinct distances and elevation profiles:
- Arc 100M: 173 KM, 5507 M+
- Arc 100K: 82.7 KM, 2708 M+
- Arc 50K: 49.4 KM, 1458 M+
- Arc 20K: 22.1 KM, 744 M+
Since its launch in 2015 the Arc of Attrition began as a single 100-mile race with 50 runners and has grown into one of the UK's larger trail running events. The programme therefore spans a wide range of distances, from the 22.1 km course up to the 173 km 100-mile option. Race descriptions and category labels are listed by organisers for each distance.
