Yes, I like it! I pick it up & read it on and off (even though I've read through it once). It's called "The Lance Armstrong Performance Program -- 7 Weeks to the Perfect Ride" by Lance Armstrong and Chris Charmichael (his coach). It is more technical and suggests a heart rate monitor for training. It definitely is for the more serious cyclist. I certainly haven't progressed to that point yet (LOL) but am going to get a heart rate monitor for training after I finish this MS150.
