Choose your distance on the day — anything from 5K to 34 Mile Ultra.

One entry. Every distance.

The course is a 7K or 5K loop, depending on the date. 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 5pm.

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 10 and 11 run here. Course 11 uses the 7K loop; Course 10 uses the 5K loop. Chilterns paths and trails from the edge of town.
9am start, course closes 5pm — a eight-hour limit. Only one course runs on any given race day, so check the date you’re entering. Parking is on site, though the access road is narrow — take it steadily on the way in.

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 5pm, giving you eight hours from the 9am start. Walkers are welcome within that.

Is this suitable if I’ve never raced before?
Yes. A single 5K 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.
