Choose your distance on the day — anything from 10K to 41 Mile Ultra.

One entry. Every distance.

The course is a 10.8K loop. You run as many laps as you want, and you decide on the day — not at the point of entry. Stop after one lap or keep going until 6pm.

Distance Laps Actual
10K 1 lap 10.8 – 11.1 km
Half Marathon 2 laps 21.6 – 22.3 km
32K 3 laps 32.5 – 33.4 km
Marathon 4 laps 43.3 – 44.6 km
34 Mile Ultra 5 laps 54.1 – 55.7 km
41 Mile Ultra 6 laps 64.9 – 66.8 km

Distance guaranteed. Because you run whole laps, every distance comes in slightly over the standard figure — never under. Your marathon counts.

Every lap passes the aid station and your drop bag, so you can reassess each time round.

The course

Courses 1, 2 and 3 run here. Each is a slightly different route, so exact distances vary a little between them. Roughly 80% trail and 20% road, through public footpaths and woodland.
9am start, course closes 6pm — a nine-hour limit. Only one course runs on any given race day, so check the date you’re entering.

What’s included

  • Manual timing with Webscorer, and a finisher’s medal whatever distance you run
  • Aid station every lap — water, soft drinks, and vegan and vegetarian food
  • Indoor bag drop and proper toilets
  • Qualified medics on site all day
  • Free parking

Common questions

Do I have to decide my distance in advance?
No. You enter the race, not a distance. Run as far as you like on the day and we’ll record whatever you complete.

What if I want to stop early?
Then you stop. Finish a lap, and that’s your distance — you keep your number, you get your medal, and nobody records it as a DNF. There’s nothing to drop out of.

Is there a cut-off?
The course closes at 6pm, giving you nine hours from the 9am start. Walkers are welcome within that.

Is this suitable if I’ve never raced before?
Yes. A single lap is a perfectly good day out, and you’ll be lapped by people running four times as far who will cheer you on as they go past.
