Has anyone tried this program? Looks like an interesting way to train with "virtual power" without spending thousands on an actual power meter. I am waiting for my "ANT-stick" to arrive and then I plan to give it a try. You do need a Garmin-type cadence and speed sensor and one of their supported trainers. I have an older Minoura rim-drive trainer that isn't listed, but it seems to be identical to a newer version that is, so I will try it out.
