"There's nowhere in the UK quite like it — a proper adventure on the best gravel around."
"The Dirty Reiver is pure joy on two wheels. The volunteers, the riders, the scenery — it all comes together to create something special. I felt supported every kilometre."
"Brutal in the best possible way. The 200 km route tested every part of me, but crossing that finish line was unforgettable. Highly recommended for anyone who loves gravel."
