For Those Who Suffer We Ride

Inspired by the courage it takes to fight blood cancer, the FireFlies will once again take on the legendary cols of the Tour de France. 

Each year since 2001 a group of riders from the Advertising, Film & Media world have come together to ride across the Alps.  We raise money to support clinical and scientific research into the causes and treatment of leukaemia and other blood cancers at the Hammersmith Hospital in London.

This year, in just eight days, we will ride 1000 kilometres and take on some of the toughest and longest climbs in the Alps.

Every penny we raise goes towards this outstanding cause.
