Beachy Head Marathon 2026: How to Prepare for the South Downs

The Beachy Head Marathon 2026 takes place on Saturday 24 October, starting at 08:45 from Dukes Drive at the western end of Eastbourne seafront, with the half marathon the next morning. To prepare for the South Downs, practise walking steep climbs, get used to running on grass and chalk, and plan to run by effort, because the organiser says the course typically takes 30 minutes to an hour longer than a road marathon.

This guide covers the race weekend timings, what the course throws at you, how to pace and fuel it, what to wear for late October on the Downs, how to get to the start, and a simple plan for the final two weeks. Edge is not affiliated with the Beachy Head Marathon. Every event detail here comes from the organiser's own website at the time of writing, and the organiser says final details are emailed one to two weeks before race day, so treat that email as the final word.

When is the Beachy Head Marathon 2026 and what time does it start?

The event runs over the weekend of 24 to 25 October 2026, its 46th year. It used to be called the Seven Sisters Marathon, and its official website is run by Visit Eastbourne. Three races are on the Saturday and the half marathon is on the Sunday. All of them start and finish on Eastbourne seafront at the start of the South Downs Way.

Times and caps from the organiser's website and FAQs at the time of writing. Check your final details email in race week.

A few practical points from the organiser's FAQs. Race numbers and timing chips are posted out one to two weeks before the event. If you entered late (after midday on 2 October), you collect your pack on the morning from the Sport Systems desk in Helen Gardens, and Sport Systems is on site from 7am on race day to sort out any race pack queries. There are no on-the-day entries and no early starts. If you are still thinking about entering, the site listed entries as open when we checked, and the FAQs say entries close when each race is full or at midday on 23 October, whichever comes first.

One thing for half marathon runners: UK clocks go back one hour at 2am on Sunday 25 October, so your 08:00 start is in GMT. Your phone should update on its own, but check any other alarm you rely on. On the bright side, you get an extra hour in bed.

What is the Beachy Head Marathon course like?

It is a full off-road marathon through the South Downs National Park, and it is tough from the first minute. The race starts on Dukes Drive and heads straight up a steep hill onto the Downs. From there the route passes through the villages of Jevington, Alfriston and Litlington, follows the Cuckmere River back to the coast, then crosses the Seven Sisters cliffs and passes Belle Tout lighthouse before dropping back down to the finish on Dukes Drive.

The organiser counts over 300 steps and 14 gates, and quotes an elevation gain of up to 1,381m across its routes, so check the course profile on the event site for your own race. The ground changes year to year. The organiser says it can be dry, damp, slippery, soft or muddy, and it cannot promise which. The big thing to know is that the Seven Sisters come late. You reach the coast with most of the marathon already in your legs, then face a run of short, steep ups and downs along the cliffs. Runners who blow up often do it there, because they went too hard in the first ten miles.

The organiser lists these marathon drink stations: the start and finish, then miles 4, 8.8, 16.7, 18.5 and 22.8. It also says checkpoints were under review and may change, with runners told in advance. Toilets are listed at Jevington (around mile 4), Alfriston (9), Bo-Peep (12), Litlington (16.7) and Birling Gap (22). Notice the gap between mile 8.8 and mile 16.7. That is nearly eight miles of hilly trail with no drink station, which is exactly why the organiser encourages runners to bring their own hydration.

How should you pace a hilly trail marathon like Beachy Head?

Forget minutes per mile. On a course like this your pace will swing wildly from one mile to the next, so watching your watch just leads to panic. Run by effort instead. For the first half, you should be able to talk in short sentences. If you cannot, slow down. The organiser's own guide is that the course takes 30 minutes to an hour longer than a road marathon, so a runner with a 4:00 road time might sensibly plan for somewhere around 4:30 to 5:00 here, and more if the ground is wet.

Walking is not failing on a trail marathon. Many experienced trail runners power-hike the steep climbs: short steps, lean slightly forward, hands on thighs if it helps, and keep moving. You lose very little time compared with running them, and you save a lot of energy. Then run the flats and the gentle descents. If you are new to off-road racing, our trail running guide for beginners covers the basics of footing, effort and kit.

Downhills deserve as much respect as the climbs. Steep, grassy descents hammer your thighs, and wet chalk can be slippery. Keep your steps short and quick, look a few metres ahead, and let gravity do some of the work rather than braking hard with every stride. Our guide to downhill running technique goes into this in more detail. On fuel, aim for something every 30 to 45 minutes from early on, and only use gels or bars you have already tried in training. The organiser says there is food on course, including bananas, chocolate bars, biscuits and sausage rolls, with vegan options, but it also advises bringing your own energy products.

What shoes and kit do you need for Beachy Head?

The organiser notes that trail or off-road shoes are a popular choice, and on a course that can be muddy or slippery that is sensible advice. Shoes with grippy lugs will feel much safer on wet grass and chalk descents. Whatever you pick, wear them for at least one long run before the race. This is not the day for new shoes. Here is a simple kit list to check against your final details email:

• Trail shoes you have already run long in, with socks that do not rub.
• Hydration belt or running vest. The organiser actively encourages runners to carry their own drink to cut waste.
• Your own gels or bars, enough for roughly every 30 to 45 minutes.
• A light waterproof jacket for wind and rain on the cliff tops, plus a cap or buff.
• Anti-chafe balm for feet, thighs and anywhere a vest strap sits.
• Music, if you must: in-ear headphones are banned, but bone-conducting headphones are allowed.
• Warm, dry clothes for after, left in the bag drop at Bede's Sports Hall, which the organiser says is open on both days.

The pages we read did not list any mandatory kit for the marathon, but rules can be added in final details, so read that email carefully.

What is the weather like on the South Downs in late October?

Honestly, it could be anything. Late October on the south coast can bring a bright, cool morning that feels perfect for running, or wind and rain blowing in off the Channel. The Downs and the Seven Sisters are open and exposed, so wind on the cliff tops can feel much stronger than it did on the seafront at the start. Rain also turns chalk paths and grassy slopes slippery, which slows everyone down.

Check the forecast for Eastbourne and the Downs in the final few days and pack for the worst version of it. If it is cold and windy, start with an extra layer you can tie round your waist. If it is warm, drink to thirst and take on salty snacks or electrolytes. The cliff edges along the Seven Sisters and around Beachy Head are high and unfenced in places, so stay on the marked route, especially in wind or poor visibility.

How do you get to the start in Eastbourne?

The organiser gives the start postcode as BN20 7RP, at the western end of the seafront in Meads. There is no official car park. Instead there is free on-street parking around the start on a first come, first served basis, with pay and display charges along parts of the seafront, so arrive early. Road closures are planned on Duke's Drive and Upper Duke's Drive.

By train, Southern runs services from London Victoria, and you can join at Gatwick Airport or Haywards Heath to avoid central London. From Eastbourne station, the start is around a 30-minute walk. The organiser also suggests the number 3 or 3A bus from outside the London and County pub opposite the station, which drops you at the start of the South Downs Way, about two minutes from registration. Check weekend timetables before you rely on an early bus. If friends are coming to cheer, the organiser suggests Beachy Head and the Seven Sisters visitor centre at Exceat as viewing spots, and asks supporters to avoid driving into Alfriston and Litlington.

What should your final fortnight before Beachy Head look like?

With about two weeks to go, your fitness is mostly built. The job now is to arrive fresh, with kit and fuel you trust. Cut your total running back over the two weeks, keep a little hill work so your legs remember the effort, and avoid anything new. For the thinking behind this, see our guide to tapering for a marathon. Here is a simple plan to adjust to your own training:

If you are running the half on Sunday instead, shift the whole table one day later. Either way, after the race give yourself at least a week of easy movement before any hard training. Hilly trail marathons often leave your thighs sore for longer than a flat road race, mostly because of all that downhill running.

How can Edge help you train for a hilly trail race?

A course like Beachy Head rewards more than just miles. Strong legs for the steps, solid calves and hips for the descents, and an engine that can keep going for five or six hours all come from mixing running with strength work. That is exactly what Edge is built for. Edge is free to use, and Edge Pro gives you a fully personalised plan across running, strength, HIIT and mobility as one programme, ready within 24 hours, with a real coach you can message anytime. Pro starts from £19.99 a month after a 7-day free trial, and Edge syncs with Strava, Garmin, Apple Health and Coros. 20,000+ members already train with Edge.

If Beachy Head is this year's race, use Edge to plan your recovery and build towards a spring goal. If it is next year's, now is a great time to start the strength base that makes those Seven Sisters feel a lot kinder.
