Can you describe the terrain and technical difficulty?+
The course is approximately 85% off-road, mostly consisting of smooth fire roads. However, there are sections with deep gravel and rougher, more rugged trails, particularly on the loop heading into Scotland.
What level of rider is this event suitable for?+
While the shortest 57km route is suitable for all abilities, both the 114km and 186km distances are considered very challenging due to their long distances and significant climbing, best suited for experienced riders.

Participants on the 186km Triple Crown route should expect to be in the saddle for most of the day, with estimated completion times ranging from 9 to 12 hours.

Riders can expect fully signed routes, GPX files, well-stocked checkpoints with food and drink (including tea, coffee, cake, sandwiches), mechanics at aid stations and the village, and support vans for major issues. A beer is also offered at the finish.
What are the recommended bike and tyre types?+
Gravel bikes are recommended for this route, though hardtail mountain bikes are also suitable. Standard all-rounder tyres between 40-50mm are advised.
