I ran almost every day from July of 1985 until July 2005 when I bought a road bike. After a couple rides I thought, "dang, this is a much better way to get around". I just about quit running cold turkey, but still do a few runs in the off season to remind myself how much it hurts. Also, I have to get back in running shape for the Thanksgiving Turkey Trot at Crystal Springs, a race I've been going to for 18 years straight on that classic XC course that I've raced on over 50 times.
I went for a 35 minute run yesterday, my first real run this year. I felt great for the first 10 minutes, then a little less great for the next 15 minutes, then pretty crappy for the last 10 minutes. But the worst thing about it is how I feel today. My quads, calves, shins, and hamstrings are totally sore!
Running is evil!
I think I'll go 2 or 3 times next week.
If I stop hurting so much I may even try a duathlon.
