Didn't have much time this morning and won't have any tomorrow, so just a short ride. Decided to try some repeats on a hill I need to conquer. It's about 1km at 5%, then a little level shelf, then another 5% for a couple hundred meters. Last time I tried that hill I had to break it up into 4 stretches for hr recovery. The time before that I cross-trained about 2/3 of the first hill. This time I only needed one break halfway up the long stretch, then did the rest and spun along the shelf for recovery before the last little climb. Did that twice, then headed home. I'm thinking I should add this as a detour on my way home from work a couple times a week. That should help. The route home is otherwise all downhill.
