Conquer one of England's most ancient trails at The Ridgeway Challenge on Saturday, May 30, 2026, an epic 86-mile (139 km) point-to-point ultra-marathon following the entire length of the historic Ridgeway National Trail. This UTMB World Series Index Race starts at the iconic Ivinghoe Beacon in Hertfordshire and finishes at the mystical Avebury Stones in Wiltshire, sending you on a journey along a path used for over 5,000 years. With a generous 28-hour cutoff and 6,060 feet of ascent, the event tests endurance and self-sufficiency on a route that traverses the Chiltern Hills, the Thames Valley, and the high chalk downs of the North Wessex Downs. The race is renowned for its exceptional organization by Runaway Racing, featuring eight well-stocked checkpoints, mandatory GPS tracking, and the option for crew support and pacers from Goring-on-Thames onwards.
Your entry includes a prestigious finisher's medal, comprehensive event support, and the unique opportunity to be part of a small, elite field of just 250 runners on this iconic route. Early registration is strongly encouraged, not only for the best price but also for the flexible 90% credit withdrawal policy if needed more than four weeks before race day. This is a true bucket-list adventure for experienced ultra-runners seeking a deeply historical and beautifully scenic challenge. Will you answer the call of the ancient path? Entries are now open and selling fast—secure your place to run the length of Britain's oldest road.
