Autumn 100

18th Oct 2025

Approved TRA permit no.7737

The Autumn 100 is a 100 mile continuous trail race based out of the villages of Goring & Streatley on the river Thames. The course reflects the shape of a cross and takes runners on a series of 4 different 25 mile out and back spurs using sections of both the Ridgeway and Thames Path National Trails. Runners will depart from Streatley and make their way on Spur one to Little Wittenham on the first out and back section on the Thames Path. On returning to Goring, runners will be faced with the more challenging second spur of the course, out to Swyncombe Farm on the Ridgeway before returning to Goring a second time. Spur three takes runners west on the Ridgeway to Chain Hill before returning to Goring for the final leg on the Thames Path to Reading and return for their 100 mile finish. Runners must finish within 28 hours total time to be classed as a finisher.
