If you and your friends are after a fun new challenge then look no further than the Muscle Acre run.

You will need to challenge yourself as you run through hilly farmland and power through the obstacles which will include mud, water, ditches, walls, tyre climb, rig, muddy wilderness, monkey bars, treehouse and a few surprises. You will need to dig deep and show true determination to complete the course. 

It's not just a run it is an experience and even if you don't enter as part of a team, we actively encourage teamwork and we hope that you will help your fellow participants to complete the run.  You will meet some like minded people and may make some new friends.

Although the course is tough and challenging it has a fun atmosphere and we hope that you will finish the course still smiling!

PLEASE NOTE - We are a UK & Euro Qualification Race so, the first 10 (or 50% if less than 20) runners in each age category will automatically qualify for the UK and Euros Championship.  You will need to show a screenshot of your timing at a qualifying race to OCRA when you register for the Champs.


Event details and schedule

Before you leave home please make sure you have everything you need to make your event as enjoyable as possible, including a copy of your confirmation email, to be provided at registration and a change of clothing.

It would be helpful if you could please travel with a friend or your team mates to the event as this will help keep parking issues down and will also help you and your friends discuss tactics or build up the banter in anticipation of the run.

On arrival, you will be welcomed and guided by our parking marshals.

Registration will open at 09:00 and you must be registered at least 20 minutes before your wave.

A safety brief followed by a warm up will commence 20 minutes before the start of each wave.
