I did the ride to conquer cancer last year with my wife and two friends and had the BEST time!!! If your interested I suggest that you sign up soon, the popularity of this event is growing and they will close off registration soon.
We only started riding in February/March and the 200kms were not that bad, the first day was the toughest since you had to climb the escarpment but we did it and actually signed up on the end of day 1 for next year.
The $2500 is alot of money to raise and all of it goes to PMH but if you start now it will come really easy. If you need ideas let me know and I can help you out.
Included with your registration fee is a tshirt to wear while fund raising and you also get an awesome jersey to wear during the ride.
