View all races for Sep 2026

The Two Towers is a 50K night trail ultra through the Surrey Hills, following a fully marked single loop from Mickleham. The route explores the North Downs and surrounding countryside, taking runners through woodland, open downs, valleys and rolling trails with approximately 5,780ft of elevation across the course.

Runners tackle a varied and demanding route that passes through Norbury Park, Fetcham Downs, Ranmore Common and the Greensand Way before climbing to Leith Hill Tower. The return journey includes further sections of the North Downs Way, Denbies and Box Hill before heading back towards Mickleham. Three stocked aid stations support runners along the way, while glowsticks, signs and tape are used to mark the night course.

With a nine hour overall cut off, the event is designed to accommodate experienced ultra runners as well as those taking on their first night ultra. Mandatory kit includes primary and backup lighting, waterproof and warm layers, emergency equipment and sufficient hydration capacity, reflecting the challenging nature of completing a long distance trail race through the night.
