I am looking to become a better climber. I have hills....but mostly rolling. There are a few 3-4 min climbs...but nothing bigger around locally. From what I've read, becoming a better climber can be achieved without a lot of hill work...just wondering what types of workouts those would be. I am training for IMLP (2013)...and would like to be as prepared as I can for the climbs. I've recently starting doing threshold work on the trainer...keeping it simple (5 min at AT/5 min recovery z1) for an hour or so. Any advice would be greatly appreciated.
