you have to pay to enter, a bit annoyed as I can't afford to do it, it used to be free, now it's £14.99 entry fee. The cause is cancer research which is very close to my heart after losing 3 people to cancer I would love to do it, just very dis heartened as to why you have to pay an entry fee to the organisers when you are raising money for charity? Sorry rant over lol.x
