The Tour 21 2025
Campaign by Cure Leukaemia (RCN 1100154)
The Tour 21 in 2025 will see a team of amateur cyclists take on all 21 stages of the 2025 Tour de France route, one week ahead of the professional race - with the aim of raising over £/$1million for Cure Leukaemia.

Story

During the last 2 summers, I completed all 21 stages of the Tour de France (both 2024 and 2025 routes) on behalf of Cure Leukaemia, alongside a small team of amateur cyclists.

Together we raised over $2,000,000 (2 Million US Dollars) for Cure Leukaemia and we aren't stopping.

On Friday August 29th 2025 I'll be attempting to break the Guinness Book of World Records for longest distance in 1 hour on a fan bike. More details to come!
