I just got back from an hour of speed skating. Speed skating used to be my sport of choice until I switched to cycling 7 years ago. IMHO, it's great for cardio work but it used completely different muscles than cycling. I use it now when it's too cold to ride. It's easier on the knees running. I still enjoy skating but I prefer cycling much morelexington476 said:Anyone have any idea how doing indoor inline speed skating works on base miles?
