Several years ago, I wanted to place in the top 3 in the Mount Evans Hill Climb, so I spent every spare minute on my bike. Cross training did not cross my mind (pardon the pun). That same year, I took my then boyfriend on a trip home to Montana. I wanted to show him Glacier National Park and do some hiking. True to form, we hiked the steepest trail we could find, passing as many other hikers as possible. We reached a beautiful vantage point in record time, took some pictures and started hiking back. Within a quarter mile (maybe less) I had developed “sewing machine legs.” I looked like someone with a neurological disorder. I stumbled the rest of the way down, mostly peg-legged and collapsed on the nearest bench.
