UK fall classic: fast, runnable 100-mile trails with crisp weather and elite-level organization.
Autumn 100 (A100) is a 100-mile trail race held by Centurion Running on October 17–18, 2026, starting at 9:00 AM from Goring-on-Thames in Oxfordshire, England. The course covers 161 km with approximately 1,500 m of gain (~9.3 m/km) — placing it in the top 5% flattest measured courses in the DTR database at rank 372 of 383 by elevation density. The format is four 25-mile out-and-back spurs, all returning to Goring Village Hall race HQ, alternating between the flat Thames Path river sections and the hillier Ridgeway ancient trackway. 69.8% of the course is flat terrain; the average uphill gradient of 4.64% is the 371st gentlest of 390 measured courses in the database — virtually every climb is runnable. The men's course record is 13:58 (Geoff Cheshire). Entry costs £1.57/km (£220 UKA affiliated). London Heathrow (LHR) is approximately 52 minutes away by road, with good train connections to Goring. Founded in 2012 and organised by Centurion Running — the UK's most established 100-mile series — the A100 has approximately 170–175 finishers in recent editions. Entry requires a sub-15hr 50-mile finish since January 2021. It suits runners targeting their first 100-mile finish or a fast-course 100-mile benchmark, particularly those coming from road or flatter trail backgrounds.
