Brilliant, challenging ride around the best gravel in the UK!
This is why I cycle!
Savage but Brilliant!
If you ride bikes , then you have to do this”
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 is a challenge not a race - you make this event as competitive as you want…there will be no podiums but you will receive your time and ranking.
