Ultra Challenge Series

Take on an ultra challenge for us this year. You can choose to walk, jog or run distances from 10, 25, 50 or 100km.

Walk, jog or run

These unique events, hosted by Action Challenge, range from coastal paths, lakesides, well-trodden footpaths and tough hills across England. Whichever challenge you choose, you’ll get our full support all the way including regular rest stops, free food and drink, medics, marshals and a massage, plus plenty of fundraising support.

As Breast Cancer Now are an official partner of Action Challenge, you get a 50% discount on the ‘Full Sponsorship’ registration fee when signing up to support us.
