The biggest gravel climbing challenge of 2024!

After a successful test event in '23, This spring sees the launch of our belter long distance event, The Grand Old Dukes! 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 brand-new 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 Cobeland, you will take in 111 miles of varied terrain over one massive single loop. You’ll experience our infamous Gravelfoyle superhighway, flowing fire roads, winding roller coaster trails, technical single track, punchy climbs and awesome descents – you’ll get it all!

Come prepared for a full day of adventure, grind, sweat and joy. We’ll keep you safe with our marshals and medics, fuelled with our feed stations and rewarded at the end of a glorious day with a completers medal.

This stunning route will be suitable for both gravel bikes and xc mountain bikes. There will be generous cut-off times for each stage with riders redirected via the road.

What you get with your entry:

• A beautiful waymarked and marshalled 111mile route around the lochs and glens of the Trossachs
• Three feed stations to keep you fuelled
