Abingdon Marathon 2026: A Guide to the PB Course

The Abingdon Marathon 2026 takes place on Sunday 18 October 2026, starting at 9am on the athletics track at Tilsley Park in Abingdon, Oxfordshire, on a new course that the organisers describe as mainly flat with very gentle inclines. It is a small, volunteer-run road marathon with a reputation for personal bests, and the 2026 race is listed as sold out, so this guide is for people who already have a place and want to make the most of it.

Below you will find the race-day timings, what is new about the course, how to pace a flat marathon, where the drinks and toilets are, a day-by-day plan for the final 10 days, and what to eat in race week. Edge is not affiliated with the Abingdon Marathon or its organisers. The details here come from the race website and the 2026 runner booklet at the time of writing, so check the organisers' latest updates before you travel.

When and where is the Abingdon Marathon 2026?

The race is on Sunday 18 October 2026 and starts at 9am. The organisers' website and 2026 runner booklet both give this date, and neither calls it provisional. The start and finish are on the running track at Tilsley Park, on Dunmore Road, about a mile north of Abingdon town centre (postcode OX14 1PU). You finish in front of the grandstand, which is a nice way to end 26.2 miles.

The 2026 runner booklet sets out this race-day timetable:

The time limit is 6 hours. The booklet says runners who look likely to finish outside it will be told at 14.5 miles, and anyone still outside the limit at about 23 miles will be offered a lift back to Tilsley Park. Entry is for over-18s only.

What is new about the 2026 Abingdon Marathon course?

The organisers announced a new course for 2026. They say they have kept the highlights of the old route and dropped some of the less interesting sections. The booklet confirms the new course has a UK Athletics certificate of course accuracy and describes it as mainly flat, with any inclines being very gentle.

In simple terms, the route works like this:

• You start on the track and head out towards Radley on Dunmore Road and Twelve Acre Drive, on closed roads.
• You pass through Abingdon town centre, with the market square near the 5-mile mark.
• The middle of the race is two laps of a loop through Drayton, Milton (including Milton Park) and Sutton Courtenay. The first lap ends at about 14.5 miles and the second at about 23 miles.
• You come back through Abingdon and finish on the Tilsley Park track.

Two things to know. First, the race is not run on fully closed roads. Some sections are closed, but you should keep to the left-hand side and always follow the marshals and police. The booklet also warns that parts of the course are narrow. Second, the headphones rule is strict: only bone-conduction headphones are allowed, and anyone wearing in-ear or ear-covering headphones, even a single earbud, will be disqualified.

Why is Abingdon known as a PB course?

The organisers describe it as flat and fast and say it is a great race to go for a personal best. A few things help:

• Flat roads. The course is almost all on roads, with only gentle inclines, so you can hold a steady rhythm.
• A small, club-heavy field. The organisers say it will always remain a small marathon, and they report that over 300 UK running clubs were represented in 2025. You are likely to find people running a similar pace to you all the way round.
• Mid-October timing. Autumn mornings in Oxfordshire are often cool, which tends to suit faster running, although rain and wind are always possible.
• Age group rankings. The race is a qualifying event for the Abbott World Marathon Majors age group world rankings. The booklet says you need to register through the Abbott World Marathon Majors runner portal for a qualifying time to be recognised.

The race has been running since 1982 and 2026 is its 42nd edition. It is organised by a volunteer committee drawn from local running clubs, and it is run on a not-for-profit basis.

Can you still get a place in the Abingdon Marathon 2026?

Probably not this year. The race website lists the 2026 event as sold out and offers a waiting list. The entry page says official transfers are only handled through Eventrac and that transfers are now closed for this year's race. The organisers also say they do not run a deferral policy. If you missed out, the booklet gives a provisional date of Sunday 24 October 2027 for next year's race, and the organisers say entries generally open in mid-February.

How should you pace a flat marathon like Abingdon?

Flat courses tempt people to bank time early. It rarely works. The best plan for most people is even pacing, or finishing very slightly faster than you started. Our complete guide to marathon-day pacing goes into this in detail, but here is how it applies to Abingdon.

• Miles 1 to 2 (closed roads towards Radley). The field is fresh and keen. Aim to be a few seconds per mile slower than goal pace. You lose very little and save a lot of energy.
• Miles 3 to 5 (into Abingdon). Settle into goal pace. Parts of the course are narrow, so do not waste energy weaving past people. There is plenty of race left.
• First lap of the loop (to about 14.5 miles). This should feel controlled, almost easy. Start fuelling here if you have not already, and take water at the stations.
• Second lap (to about 23 miles). This is where the race is won or lost. Knowing the loop from the first time round helps. Break it into chunks: Drayton, Milton Park, Sutton Courtenay.
• Last 3 miles (back through Abingdon to the track). If you have paced well, this is where you can push. Save your last effort for the track.

Use the mile markers rather than your watch alone. The course is marked at every mile, and GPS watches often read a little long over a marathon because you rarely run the exact measured line. Checking your split at each marker gives you a more honest picture of where you stand.

Where are the drinks, fuel and toilets on the course?

According to the 2026 booklet:

• Water roughly every 3 miles, in small paper cups. Pinch the top of the cup to drink while moving.
• Sports drink (Active Root) around miles 11.5, 14.5, 19.5 and 23. If you have never tried it, either test it on a training run or stick to what you know.
• Fruit at about miles 10.5 and 19.5.
• Self-fill water points at the five water and drink stations on the Milton Park loop, if you carry a bottle.
• Toilets roughly every 3 miles on the course, plus toilets at Tilsley Park.

The organisers do not list gel stations, so carry your own gels or chews and use the ones you have practised with. A common approach is to take something every 30 to 45 minutes from early in the race, with water, but follow what has worked in your long runs.

What should your final 10 days before Abingdon look like?

The hard work is done. The final 10 days are about arriving fresh, not getting fitter. Cut your running volume, keep a little marathon-pace work so your legs remember the rhythm, and prioritise sleep. If you also lift or do HIIT, drop heavy lifting and hard intervals now and keep any strength work light. Our marathon tapering guide explains why this works. Here is a sample plan to adjust to your own training:

Feeling flat, heavy or a bit niggly during a taper is very common. It usually passes. Resist the urge to squeeze in an extra hard session to check you are still fit.

What should you eat in race week?

Keep it simple and familiar. For most of the week, eat normally. Over the last two or three days, make carbohydrate the main part of each meal (rice, pasta, potatoes, bread, oats, bagels) and go a little lighter on fibre and fat, which can sit heavily in your stomach. You will probably feel a bit heavier as your body stores carbohydrate with water, and that is normal. Our guide on what to eat the week of a marathon has meal ideas for each day.

With a 9am start, breakfast at around 6am gives you time to digest. Choose something you have eaten before long runs, such as porridge, toast with jam or honey, or a bagel with banana. Sip water through the morning rather than drinking a lot at once, and have a small snack or a gel around 15 to 30 minutes before the start if that suits you. Do not try anything new on race day, including the sports drink on course.

How do you get to Tilsley Park and where do you park?

There is no runner parking at Tilsley Park on race day, and you should not park on Dunmore Road or nearby residential streets, which form part of the course. Instead, the organisers list five free race car parks that open at 7am: Abingdon and Witney College, Dunmore Court, St Helen and St Katharine, Larkmead School and The Manor Preparatory School. The furthest is about a 25-minute walk from the start, so leave plenty of time. The booklet also mentions roadworks around north Abingdon and asks runners to car share where they can.

There are no direct trains to Abingdon. Early Sunday buses from Oxford and Didcot are limited, so check timetables in advance if you plan to use them.

Race numbers are posted out before the race with the timing chip attached. Do not remove the chip, fold the number or cut it down, and fill in the medical details on the back. Your bag label comes attached to your number too, so detach it carefully and fix it to your bag. The venue has changing rooms, showers, toilets, bag storage and a quiet space before the start. At the finish there is a medal, a finisher's headwear and a drink and snack, plus sports massage for a £15 donation.

What should you pack for race morning?

• Race number, pinned at all four corners, with the details on the back filled in.
• The shoes and kit you have tested on long runs. Nothing new.
• Your gels or chews, plus a spare.
• An old top or bin bag to keep warm before the start.
• Anti-chafe balm, plasters and a rain layer if the forecast is wet.
• Warm, dry clothes and a snack in your bag for afterwards.
• Bone-conduction headphones only, if you want music.
