What is the date for 2025 and when do Entries for Open? 

Entries for the 2025 event will open Saturday 31st August 2024 at 1000. Race Date is Saturday 9th to Sunday 10th August 2025.

How tough is the course? 

The course is 103 miles long and has 11,000 feet of climb/ gain and a similar level of descent. Roughly translated the route varies between undulating and hilly. There are no ascents lasting more than a few minutes except for Box Hill, however sections of the course are technical and make for hard running. There are some short sections of stairs involving climbs or descents from the steepest points. In terms of terrain, roughly 80% of the course is on trail and around 20% on the road. If it is wet in the lead up to the race or on race weekend itself, some sections will become muddy and require due care and attention. Expect a real mixture underfoot including road, pavement, soft woodland trail, mud, sand and more hard packed chalk trail. The scenery on some sections of the North Downs Way is really quite stunning. There are individual sections particularly early on that show off some of the best of the English Countryside. Overall, the extremely varied, sometimes difficult underfoot conditions as well as the number of sharp turns and short and steep climbs and descents make for slow going in places and push runners to lean on many different skillsets. Road running, crushed gravel, rocky trail and soft sand trail feature alongside smooth and rolling non-technical single/ double track running.

Is there mandatory gear to carry on race day?

Yes. There will be kit checks prior, during and after the race. Runners must carry the following mandatory equipment at all times. A time penalty of one hour will be imposed for any item found to be missing at any point on course. Please refer to this page for explanations on the inclusion of the below items. 

There are many options regards kit for fulfilling these requirements and those of other events. We stock what we believe to be the best options at our online store available by clicking here under the Mandatory Gear Section. Please ask us if you have any questions.

Are there any road crossings or gates/ stiles to negotiate? 

Absolutely yes. Whilst the North Downs Way is predominantly trail, some of it is on road. There are sections of the course where you will be running along both single and double lane carriage ways. The majority of these are very quiet country roads, however the trail does appear at busy road junctions, at some points abruptly and therefore you must be alert at all times. The busiest junctions will be signed but NOT marshalled. Runners pass along the course entirely at their own risk. Much of the NDW is on private land and as a result there are gates and stiles to negotiate throughout the length of the course. All gates must be closed properly after you make your way through. 

Will there be live updates during the race for friends and family to follow? 

Live tracking will be available throughout the race, so that all runner positions are available at all times. The tracking page together with a live leaderboard with check point times will be published as runners in the lead up to the race.

What happens if I need to drop out during the race?

If you need to drop out of the race, it is your responsibility to get back to where you need to get to but we will endeavor to help you as much as we can. If you have to drop please do so only at an aid station. Please inform the aid station captain on arrival that you intend to drop and whether you need assistance - you must hand in your bib number and tracker at that stage. If you need to drop out away from an aid station you must phone the race director immediately on the number provided at check in. You must then arrange to bring your bib number and tracker to the nearest aid station, or to the finish. DO NOT go home with your tracker under any circumstances. If you drop at an aid station, the Aid Station Captains will inform you if it is possible to get transport to the finish or public transport. There is a sweeper bus, however it may be that you have to wait some considerable time so please be patient with the volunteers. The bus travels with the cut offs.

There will also be a fixed medical team on hand at the finish line. Individual first aiders/ medical volunteers will also be present at some aid stations.
