Super simple orienteering in the woods

4.2 MPH

Run a 4.2 miles per hour, every hour for as long as you can up to 12 hours.

The event will take place on the 5th of September. The first group* of runners will set off at 10am.



Out of stock



The marathon takes in the half marathon route and then extends out to Minwear Woods and the surrounding trails, some of which are along a stunning river bank.

We have opened up some old and unused rights of way to give you the chance to run some lesser known trails. You can expect some tough little climbs, some ancient ruins and probably a fair bit of mud!

There are feed stations on the route, they have water and jelly babies!

We welcome all abilities from seasoned speedsters to first timers looking to complete their first trail marathon.

There is a cut-off time at the 11 mile mark of 2 hours 30 and at 22 miles of 5 hours 30.
