In the winter of 1989 I slipped on a patch of ice while running and broke my leg. It was a complicated break and took a long time to heal correctly (I had a little "play" in that ankle for about 6 months). So I didn't run at all that year and instead rode a lot of bicycle (including the Chequamegon 40 MTB classic). I finally started running again over a year later but initially had some pain and had to take it really easy for quite a while. But the patience paid off and I had some of my best races that summer (4:15 half IM and 2:01 olympic).
