“Oh The Grand Old Duke”……he climbed 10,000ft!

This spring will see the return of the toughest gravel challenge in the UK! Inspired by the iconic Dukes Pass which takes you from Aberfoyle on the edge of the National Park into the very heart of the Trossachs we have created a monster route which is predominantly off-road. You’ll be rewarded with open vistas and panoramic views of our iconic lochs and mountains…and of course excellent riding.

Starting in Aberfoyle, you will pedal north taking in 111 miles of varied terrain over one massive single loop. You’ll experience our infamous Gravelfoyle superhighway, technical single track, flowing fire roads, winding roller coaster trails, punchy climbing and awesome descents – you’ll get it all!
