I used to run to keep fit and stay fit for scuba diving. Knee said no to running. Then turned to cycling with encouragement of a friend. Real addict now. As of today did 3,060 miles so far this year. On the bike at least 4 days out of 7.
I suffered a rotor cuff tear April 25 and in the intrem have still put on almost 500 miles even though it has slowed me down a bit. Love cycle touring.
Since I have not been diving once so far this year, guess cycling has almost replaced diving. Sometime in the Fall I will get in a dive.
