Had a hard run this morning, I was in a hurry after my Monday run and didn't stretch that day --- it didn't seem to affect me in my regular activities or in my swim, but boy did I notice today. About 5 minutes in my right quad (thigh muscle) felt tight, hard even, and painful, and I had to keep stopping, walking a bit, and then starting up again. I tried running slower, I tried switching to the other side of the street (don't laugh, those of you who don't run, the slope of the sidewalk can make a difference with these things), and it wasn't until I got about a mile and a half in that I thought to stretch. Problem solved. I made sure to stretch my trouble spots when I got home, for sure.
The other thing I have to watch out for these days... peeing. Namely, that going too fast, or going too vigorously downhill, sets off a need to pee that is unignorable, and I'm typically able to ignore such things (when running). I've been running routes that bring me by decent public restrooms, though the last few weeks I've only had to make use of them during the first half of my run, then I'm fine. But no, today I had to take one descent a little too quickly... luckily I knew my yoga place was open that early and they kindly let me come in and use the facilities. I have to remember, speed is beside the point these days, it's just about going the distance (and enjoying myself in the process).
Sweet Pea is beginning to add commentary to my activities... kick, kick, kick, just like Buddy... but why right before bed?
