2026 Abingdon Marathon - Oct 18 Countdown

Q: What is the Abingdon Marathon route?

The Abingdon Marathon starts and finishes on the athletics track at Tilsley Park in Abingdon, Oxfordshire. Runners head out along closed roads towards Radley for the first couple of miles, then complete a two-lap loop on quiet roads through the villages of Drayton, Milton and Sutton Courtenay, before returning through Abingdon to a finish on the track in front of the grandstand. The 2026 edition uses a refreshed course that keeps the highlights of previous years.

Q: Is the Abingdon Marathon flat and good for a PB?

Yes - it is one of the flattest and fastest marathons in the UK. The course runs over gentle Thames Valley lowland with only minor undulation and no real climbs, and the whole route sits in a tight band of roughly 50 to 72 metres above sea level. It has a strong reputation as an autumn personal-best race. Plan your target with our pace calculator.

Q: How do I enter the Abingdon Marathon 2026?

Entry is open to the public on a first-come basis (no ballot) through the official site at abingdonmarathon.org.uk, with registration opening in February. The field is capped at around 1,200 places and the race sells out fast - often within a short window of opening - so enter early or join the waiting list. Entry is around 63 GBP, with a small discount for affiliated club runners.

Q: What time does the Abingdon Marathon start and what is the cut-off?

The marathon starts at 09:00 from Tilsley Park on Sunday 18 October 2026. There is a 6-hour time limit, with a discretionary tolerance of up to 15 minutes; runners much slower than 6-hour pace may not receive an official result. Use our finish-time calculator to check your projected time against the limit.

Q: Does the Abingdon Marathon count for Boston qualifying or a Good For Age standard?

Yes. The course is UK Athletics licensed and accurately measured, so a time run here is valid for both Boston qualifying (BQ) and a London Marathon Good For Age (GFA) entry. There is no qualifying standard to get in - your finish time simply counts. Abingdon is also one of only eight UK qualifying races for the Abbott World Marathon Majors Age Group Rankings. Check your target against the standards with our Good For Age tool.

Q: How big is the Abingdon Marathon field?

It is deliberately small and friendly, capped at about 1,200 entries, with roughly 1,000 finishers in a typical year. The organisers state they will always remain a small marathon - facilities at Tilsley Park and a few narrow points on the course limit the field. That intimate scale, fast course and club-runner crowd are exactly why it draws PB hunters from across the country.

Q: What is the weather like for the Abingdon Marathon, and how do I get there?

Mid-October in Abingdon is typically cool and sometimes damp, around 11C (52F) at the start. Abingdon sits just south of Oxford; the nearest mainline rail hubs are Oxford and Didcot Parkway, both a short bus or taxi ride away, with London around an hour by train. Roads around Tilsley Park and towards Radley close on race morning, so leave plenty of time to reach the start.
