After a layoff of 2 weeks following a couple months of not much running anyway, I'm returning to it.
Tuesday I did walk/run intervals: 5 minutes walking w/ my mother's dumb dog Woody and my own good dog Journey; then with just Journey I did 4 of run 5/walk 5, then run 1 more minute and walked the last 4 = 35 minutes total.
My quads were sore the next day.
Actually still a little sore today, but I went out and did the same, adding 1 minute to 3 of the runs. It went like this:
With Journey & Woody: walk 5.
Just Journey: run 6, walk 5; run 6, walk 5; run 5, walk 5; run 2, walk 3. Total 42 minutes.
We'll see how my quads do. And my ankles. I have not turned an ankle for almost a year, since I went to minimalist running shoes (Saucony Kinvara's). In these shoes, which aren't much more than an ultralight upper attached to an outsold with just a suggestion of midsole, my feet are more flexible and I can feel the surface I'm running on. If I step on something uneven, I feel it and correct my foot. In regular running shoes, by the time I realize my foot it turning, it's too late to correct it. Hiking boots are the same. In fact, my concern about my ankles now comes from having wrenched both of them a few weeks ago, backpacking in leather boots. Same thing: My foot couldn't tell where it was landing. So I'm returning my hiking boots (REI accepts returns with no time limit even if they're used) and planning to hike in my mini running shoes, or maybe even those Vibram 5-Finger "shoes." Seems like the less shoe I have, the better my feet are.
