Since last here I've taken up running again. A couple of years ago I read an article in Men's Health by Christopher McDougall. Since, he has released Born to Run, and excellent book about a tribe of runners in Mexico. I bought both the Nike+ and a pair of VFFs (Vibram Five Fingers). I had bought a pair of Fila running shoes back in 2007, but hardly used them since I was running on a treadmill; I have no discipline, so it is too easy to hop off when I get a little tired.
Since it has been since 1986 since I've run with any regularity, I'm easing into this. I bought the VFFs because I've always preferred being barefoot and think that the barefoot running movement is looking the correct direction. The first day I ran with them on, I went to a local park and ran too far since it was so easy. I had read/heard that I needed to be careful not to go too far, but figured since I was so out-of-shape that I wouldn't be able to go far. Two days later I was hobbling around like an old man with stiff calves.
Now I run most days in the Filas since I can use the Nike+ with them (My VFF Sprints don't have a good place to put the sensor). I've found though, that I can run farther on the days I wear the VFFs. The stuff I hear about ChiRunning may be true. I'll have to get that book and read it too.
