hey adkoch/Angie,
You're right...Sally Edwards has a ton of heart rate training info...she also co-authored a "heart-cycling" specific book with Sally Reed. it's a terrific resource for incorporating into anyone's training program whether you're a roadie, mtb'er, spinner, triathlete or all of the above! There are a variety of workouts to use, either indoor or out. I found it at a large national bookstore chain but Sally also has a website, in case you want to check it out (Sally is the national athlete/spokesperson for the
Danskin Women's Triathlon series too):

Lots of good info to help anyone in learning more about the most important muscle in their body...have fun!
