Wendover Woods
From £65
THE EDGE
9 hours.
A trail in the woods.
As many laps as you can.
And one simple rule:
Every lap faster
than the one before.
the course
The Edge takes place in the picturesque surroundings of Wendover Woods, which is easily accessible from London.
The course covers 6km of trail paths with around 150m of elevation gain per lap.
Every lap is the same course. The question is: can you complete it faster each time?
the CHALLENGE:
Every lap faster.
You start as slowly (or as quickly!) as you like, and you control how quickly you ramp up. The only rule? Each 6km lap must be faster than the one before. This includes rest time.
You have up to 9 hours to complete as many progressively faster laps as you can.
Your race ends when you fail to beat your previous lap time, or decide to stop.
Either way, you have reached the edge.
HOW HARD DO YOU
DARE TO PUSH?
Every lap raises the stakes, and every decision matters. Time and time again, you’ll face the same question: how much have you got left?
The Edge isn't simply about endurance or speed. It's about intelligent pacing and how hard you dare to push…

FAQs
-
Not at all.
Your medal is earned once you’ve completed at least 3 progressively faster laps.
You’re welcome to stop there, or you can keep pushing to finish the race by completing laps until the final hour!
-
Nope!
You can start as slow as you like, and you control how quickly you ramp up. There’s no minimum pace. You just need to complete each lap faster than the one before.
The Edge isn’t about being the fastest. It’s about intelligent pacing and how hard you dare to push. That will look different for everyone.
-
Absolutely.
But the clock keeps ticking, and time spent resting counts towards your lap time. So you’ll need to factor rest time into your pacing strategy from the start.
-
Your race ends if you fail to beat a previous lap time. There are no ties, resets or second chances.
But failure isn’t necessarily a bad thing. It means you’ve reached the edge. It’s what this race is all about.
-
Very unlikely.
The course follows existing trail paths and will be clearly marked.
You’ll also receive the course map before race day, so you can download it to your phone or watch.
-
You must be aged 20+ to enter, and have recently completed a half marathon or longer distance
