I was asked to attend with a friend, we signed up for the Yorkshire 2017 race. Its 10 miles with about 25 horrible obstacles. Its a sort of military type of event but the earnest is on team work and helping each other get around. I paid for a pair of Merrill trainers that are made for Tough Mudder and they are awesome- great grip in the mud and water dry's quickly. The event is quite expensive (but worth it) and the only think I thought was a rip of was the parking- very expensive. Everyone is helpful and fun and there is a real feel of community there.
