I may be in Colorado with some friends this summer. Some of us ride, while some do not. I would like some advice on how to find road routes while I'm there. I would like to ride between 40-100 miles/day depending on terrain for 4-6 days. We've considered signing up for the Bicycle Tour of Colorado to benefit from their pre-planned routes and SAG support. Would this be a good option or is it better to create our own? Are there any books or bike shops that could help? Thank you!
