On Thursday 11/18 and Monday 11/21 we ran. On the street. It was horrible, and not so bad. A mile course downtown.
I have never been able to run for distance. Even when I wrestled, and when I was in the Army, running was something I simply could not do with any success.
On 11/18 we ran about 1/2 mile, largely downhill and walked a half.
On 11/21 we ran 1/2 mile largely up the same hill. I walked a quarter and then "ran" down the final quarter.
Both times I could barely move afterwards.
Something in my physiology/psychology makes running almost impossible for me. That is, of course, why I insist on doing it.
I'll blame this on having a ridiculously high percentage of fast-twitch muscle fibers and move along.
