Our runs take place throughout the year at our permanent site in the beautiful Sussex Countryside just 5 minutes from the centre of East Grinstead (RH19 4RR – see below for full address and map). The start waves begin at 10:00am and go every 15 minutes until early afternoon.

We welcome people of all abilities and experience, whether you regularly compete in obstacle races or are thinking of making this your first one, just pick the distance that is right for you. We are a friendly run that offers encouragement and positivity not punishments, we want everyone to have loads of fun and achieve personal goals along the way, whether it’s beating a previous time, completing the monkey bars, scaling the vertical wall or working as a team to get around the course together.

If you are after a tough OCR then the 20km route is for you, we regularly see the 20km claim many a seasoned OCR runner, will you be victorious or will our energy sapping, shoe sucking, legendary mud get the better of you...!?!

The pre race warm up will be provided for each wave so please ensure you only take part in the relevant waves warm up. Everyone must attend the warm up as it includes a short health and safety briefing to ensure your safety during the run. It will also make sure you are properly warmed up and ready to go, the warm up will last approximately 10 minutes, once the warm up has finished there will be a countdown then it will be time to go!

Dehydration is one of the most common causes for not completing races. We highly advise all racers to drink fluids before, during and after the race.
There will be free water hydration stations placed throughout the course and every runner will receive a free bottle of drink when finishing.


Bring a plastic bag and change of dry clothing, shoes, wipes, and towel. There will be an outdoor cold water shower station available.  


It would be ideal to wear cross country, trail or fell running shoes which have grippy soles, moulded football boots have also been recommended in the past. Normal trainers are not ideal, however you will still get round but it might be a bit slippery.  Shoes that might be dangerous will not be allowed, there will be NO spikes allowed on the day our officials will be checking footwear on the day and if they are deemed to be dangerous you will not be allowed to run. Also you will not be allowed to run in barefeet at any time.   

We recommend that you wear lightweight clothes that will dry quickly, even if it’s cold as heavy or thick clothing will retain the water and not only weigh you down but also make you colder.  Long sleeve and bottoms might help protect you from scratches.  It’s also a good idea to bring a change of clothes with you so you can relax and enjoy yourself in some clean clothes after you’ve run.
