Did the CAS Honda experience two years ago and it was great. It was a fantastic day. You get there, you get your kit, you pick your bike, you follow some dude round the course and the rest of the day is up to you, swap bikes, take a break, ride all day..... the choice is yours.
It was a top day out.
No matter how fit you think you are, you are in for a world of pain the next day!!
