Why take on an Ultra Challenge?

“On a personal note - do it! It will totally change your life! I started walking ultra-challenges back in 2014 with my best friend and it was one of the most positive things I have done! It gives you a real confidence boost. You meet such a great bunch of people at these events and everyone really supports each other. If you are going to do it, then do it for a worthwhile cause like Prostate Cancer UK to get more men talking!”

Claire, Ultra Challenge fundraiser, 2021

In 2021, Claire took on eight Ultras (yes, eight Ultras!) to help beat prostate cancer. Join Claire and hundreds of others and take on an Ultra for Prostate Cancer UK in 2022 to help fund lifesaving research and support for thousands of men and their families affected by the disease.
