About this race

Henley Basecamp, in the Chilterns countryside, anchors this demanding Chiltern 50 Ultra Challenge. This looped trail event offers a significant test of endurance for those who "Walk, Jog, or Run" through its scenic and challenging terrain. The course starts from Henley Showground, following the Thames River to the historic Henley Bridge before heading into the expansive countryside. Runners then navigate sections of Shakespeare's Way and Icknield, completing full Loops designed to be fun, safe, and rewarding as they push their limits back to the Henley Showground finish.
