What is Big Hike?

Cancer Research UK's Big Hike is a series of full and half marathon hiking challenges, held in 4 stunning locations across the UK.

Take big steps towards beating cancer by hiking through rising hills, river valleys and taking in spectacular views across the countryside.

Explore the great outdoors and raise money for our life-saving research.



Why take part in Cancer Research UK's Big Hike


We want to accelerate progress and see 3 in 4 people surviving their cancer by 2034. 

Every donation you receive will help us reach that goal. Participating in a Big Hike event while raising money means that you can be part of that fight against cancer. 


We're with you every step of the way
