oooh, another vote for Lynda Wallenfels.

I am on a second plan from her. While I don't race, I found her training very helpful. She actually WROTE a plan for me last year when I couldn't find what I needed. After almost a year and a half of very little riding, I needed to just get a base back over the winter. She then took a different plan and modified it for me.

I love the daily emails that tell me exactly what I am to do that day.
