The Restless Gravel Triathlon

THE RESTLESS - Gravel XTRI, Arrochar Alps

THE RESTLESS is an XTRI World Tour gravel XTRI event in the Arrochar Alps, Scotland, scheduled for August 22, 2026. The event offers gravel and MTB options and follows ancient drover's roads with local stories about headless beasts, dark spirits and ghostly drovers and cattle.

The course comprises three linked disciplines. The swim takes place in a deep loch from the shores of an ancient castle; the ride crosses the Arrochar Alps with large elevation gain and includes a named section called Glen Gruel of about 5 km; the run finishes at Ben Donich and the Rest and Be Thankful.

The event description notes historical context: drover routes were used to move cattle and to evade enemies, and some accounts say drovers rested near summits to recover or to honour those who died on the route. The loch used for the swim is described as very deep, reportedly deep enough to be home to military submarines in local accounts.

Distances and key figures:

• 1.8 km swim in a deep, dark loch from the shores of an ancient castle
• 50 km gravel ride in the Arrochar Alps with nearly 2000 m of ascent
• 25 km mountain run to Ben Donich and Rest and Be Thankful, 1200 m ascent

The presentation of the event frames it as a technical, high-elevation gravel triathlon developed by XTRI World Tour. Visit the organization's website for the most recent information.
