Event overview
Follow the ancient drovers’ roads once used to herd Highland cattle and escape enemies — paths steeped in legend and mystery. Tales tell of headless beasts and dark spirits haunting these rugged routes, where drovers once paused near the summit to honour those lost to the elements or robbers. On misty nights, locals still whisper of ghostly footsteps and the lowing of phantom cattle echoing through the glens.
Gravel racing has exploded in recent years, and this is its most extreme evolution. Set in Scotland’s magnificent Arrochar Alps, this XTRI adventure is tougher, higher and more technical than anything before it. Dive into a loch so deep it’s used for submarine testing, ride 50km of challenging gravel terrain climbing nearly 2,000m — including the legendary Rest and Be Thankful — then take on a mountain run to the summit of Ben Donich for views that make every step worthwhile.
It's going to be horrible!
