Riders will be pushed to the limit of human capability as they chew through 100km of road, gravel, punishing climbs, long descents and inhuman levels of lactic acid.
Only the strongest legs, lungs and minds will make it to the finish, where cycling immortality is the reward for answering the demands of this impossible distance.
How it works
Mountain Bike Marathon is unique for many reasons, but the mass start - where elite riders go first, then anyone brave enough to follow - makes it special.
Elite or amateur, the distance brings a mountain of challenges… literally.
Riders have to be exceptionally fit to traverse all kinds of terrain, from speedy flats to slow climbs and everything in between. But physical prowess will only get them so far; they have to dig deep as every metre of the 100km course tests their mental toughness.
For those lucky enough just to be watching, Glentress Forest will be the perfect stage for an event that’s going to be epic in every way.
