THE RESTLESS
The Restless is an XTRI World Tour gravel XTRI event in the Arrochar Alps, Scotland, scheduled for August 22, 2026. The race offers gravel and MTB bike options and combines open-water swimming, off-road cycling, and mountain running over natural highland terrain.
The race format includes:
- 1.8 km swim in a deep loch from the shores of an ancient castle
- 50 km XTREME gravel ride across the Arrochar Alps with nearly 2000 m ascent
- 25 km mountain run to Ben Donich with about 1200 m ascent
The swim takes place in a loch described as deep and dark and noted in the race material as deep enough for military submarines. The gravel ride includes a section called Glen Gruel described in the event notes as a 5 km very difficult stretch. The run finishes toward the summit area known locally as Rest and Be Thankful.
Routes follow ancient drover's roads that carried cattle and provided refuge in earlier times. The event text describes local legends associated with those roads, including historical accounts of people perishing on the route and stories of ghostly sightings and cattle sounds on foggy nights.
The event materials describe the Gravel XTRI as an extension of XTRI's race series, presenting a more technical and higher altitude gravel triathlon format that originated in the Arrochar Alps. Visit the organization's website for the most recent information.
