I think I've mentioned before that I'm doing Bike Tour of Colorado which is the week after RtR. I'm sure it's similar weather & elevation profiles so I appreciate all the great tips that everyone has posted.

I get nervous about the mileage and all the climbing but my friends that are travelling with me tell me I'll do fine. I'm with Leslie, slow and steady and enjoy the scenery. It's not a race, it's a vacation.

I look forward to reading about your trip and comparing our experiences!
