The Grand Old Dukes

The Grand Old Dukes – Aberfoyle, Scotland, United Kingdom

• Date: 30 May 2027

The Grand Old Dukes is an endurance gravel sportive staged out of Aberfoyle in Loch Lomond and The Trossachs National Park. Designed as an individual riding challenge rather than a podium race, the event provides chip timing and individual rider rankings without official podium presentations.

The 111-mile route features approximately 10,000 feet of climbing, traversing forests, glens, and loch-side trails across the Trossachs. The course is fully waymarked and marshalled, and it is suitable for gravel bikes and cross-country mountain bikes. Organizers enforce stage cut-off times, with road diversions provided for participants unable to meet timing thresholds.

Entry includes route GPX files, on-course marshals, medical cover, rider insurance, free event parking, and three staffed feed stations. All finishers receive a commemorative medal and a post-ride beer. Additional details, updates, and registration information are available on the official event website.
