Good luck and keep it up. But don't be surprised if you find your real biking slower than indicated by the stationary bikes. Those things are notoriously inaccurate on the high side. I work with a guy and saw him at our rec. center on a bike. Told me he was at 30 mph... looked like he was taking a short trip to the 7-11 for a Slurpee. I got on the bike when he was done, and tried to simulate my 20 mph pace (a hard pace for me to maintain). The bike said 40 mph.
