Autumn 100 2026

Goring-on-Thames, United Kingdom, 17 October 2026

This course is built as four out-and-back spurs from Goring and Streatley, using sections of the Thames Path and the Ridgeway to create a cross-shaped route. In dry conditions it is relatively flat and fast for a trail hundred, but runners still have to handle long stretches of darkness plus the chance of cold, wet and windy autumn weather. It is one of Centurion's established 100 mile races and is positioned as a fully marked, fully supported British trail hundred.

One distance, 158 km, up to 1,510 m of climb.
