Ultra Challenge's base-camp in Cirencester is the hub for a revised 100km looped route through the heart of the Cotswolds, which provides a stunning setting for 2,000 adventurers to test themselves. You can sign up for the full 100km, or you can opt to do a quarter or a half route.

There are rolling hills, villages, the magical Cotswold Way, footpaths and trails, with some fabulous views en route – and a few tough hills in between!

This is a fun and rewarding challenge with full support and hospitality included, leaving you to focus on your distance!
