Sparkour
Is a portmanteau of Parkour and Spartan. A concept originally developed as an underground running club in the heart of Essex by a group of likeminded Spartan Racers wanting to run wild. The first rule of Sparkour is its an invitation only club...
"I'm pretty fed up of tarmac bashing marathon training, I wanna run wild in the woods and streams mate, when are we going Sparkour next?"
