The Dirty Dozen

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 12th lap is a race.


Runner name field cant' be empty.
Please select an age group


Every hour you will need to complete a 4.2 mile lap. If you get back from the lap in 40 minutes, you will have 20 minutes rest before starting the next lap. Laps are not timed, you just need to get back from each lap within the hour.

Everyone who completes 1 or more lap gets a medal with a star on for each lap you completed. Medals are shown here and are for illustration purposes only, the final medal may differ from the one shown.

If you manage to complete 6 lap (6 hours) you will have done 25 miles and have 6 stars... Question is, how many you going for? Doing all 12 laps will mean you've done 50 miles!

The winner is decided by the runner who completes the final lap in the qucikest time.

Each laps starts from the race HQ, where there will be water aplenty. Your cars will also be accessible each lap, so you can bring along anything you need to get you through as many laps as possible. Marshals will be ready to help you navigate the course successfully as well as get you ready for the next lap! Check out our blog post on this event - Dirty Dozen : Research.

In order to adhere to covid exercising guidlines the event will be run in groups of 30 runners. You will be assigned a group which you have to stay in for the duration of the event. If you wish to run with your friends, you will need to buy your entries in the same order. Simply keep adding entries to your cart to do this.

The participation rules will be explained in more detail on the day.

Entry is £25.

As always, all profits go to local charities.

An event date will be announced as soon as government guidelines allow sporting events to take place. We expect this will be for groups of 100 or less, so spaces for this event will be strictly limited..
