I've become a bike rider. Not motorcycles - bicycles.... a cyclist! I used to run long distances. I actually ran 5 marathons when I was a bit younger. Many half marathons as well. But, now I cycle. Why? The "knees!"
I've run so many miles over the years that, now, the knees don't go so well. No trouble walking - but if I run, even a couple of miles, my knees let me know. So, I bought a bicycle. First I got a Trek performance hybrid. It was cheaper. I wasn't even sure if this was an actual commitment yet. I used it for one summer and quickly determined that I needed an actual road bike. Why? I couldn't keep up with folks on the road. My son would leave me in the dust and was cruising with much less effort than me.
This spring I got a carbon fiber LeMond (Trek) road bike. So much easier!! The farthest I've gone is 30 miles. I'm itching to go farther. I hope this summer to get up to 50. I could never consider that if I was still running. You can cover such further distances on a bike. Plus, you can coast if you need to rest a bit. And the feeling of the wind through your hair at 22 MPH is pretty nice. (OK - not so much hair, but you get the idea.)
Cycling has rejuvenated my exercise program. The problem is that you can't pack your bike in a suit case when traveling, like I could with my running shoes. Maybe I just won't travel as much...
See you on the road!
