Grand Old Dukes 2026

Grand Old Dukes (G.O.D), the UK’s most epic one day gravel challenge is back.

Coming into her third year, Grand Old Dukes has fast become a must-ride gravel challenge of epic proportions on all fronts.

Taking place on Sunday 31st May, participants will take on 111 miles and 10,000ft of climbing around the spectacular Loch Lomond and the Trossachs National Park located less than an hour north of Glasgow on the edge of the Highlands. The route has it all: Beautiful backdrops of lochs and mountains, every grade of gravel from Champagne to Buckfast and all on one monster loop with no crossover.

Completing the challenge is quite the undertaking, with a punchy elevation of 10,000ft to climb across the stunning backdrop… but we can confidently say that every single pedal stroke will be worth it, if not for the views alone, then for the thrilling descents. The event will also have a half option (Demi-G.O.D) for those looking to dip their toes into bigger gravel challenges, also taking place on Sunday 31st May.
