I'm looking to start training for a four day stage race taking place in August in Estes Park, CO. This is my first season on a road bike and, by the time August rolls around, I'll have a few cat 4/5 races under my belt. Basically, I'm wondering what is the best approach for training for the race. The first day is a 5k TT, then distances of between 50k and 90k in the three following days. There are some good climbs from what the profile looks like. Here's a link .Estes Stage Race. I'm going to have all of July and the first few weeks of August to concentrate on it so any advice you can give would be great. Thanks in advance.
