The Restless Xtreme Gravel Triathlon

THE RESTLESS Gravel XTRI, staged in the Arrochar Alps of Scotland, debuts August 23, 2025. The race layers a 1.8 km swim in a deep Loch near an ancient castle, a 50 km extreme gravel ride with almost 2000 meters of ascent, and a 5 km mountain run to Ben Donich with about 1200 meters of climb. The course emphasizes rugged, high-alpine terrain and technical sections, including the notorious Glen Gruel segment described as “5 km of pure hell.” The event positions itself as an intense, XTREME gravel triathlon with a mythic, historic atmosphere and challenging, scenic routes.
