I went running a bit yesterday in, well, far too long. And while I didn't really overdo it, today the muscles/tendons in the soles of my feet hurt.

It reminds me a bit of how Pratchett's described a Barbarian (was it Cohen? It may have been) as having muscles in places other men don't even have places.

I didn't know this could happen!

(Barefoot running is supposedly tougher on the suspension mechanism that is your feet/calves, but easier on the knees. Seems that is what I feel.)
