12x2-minute repeats at 5k pace (goal of around 5:20/mi). I did these at Sugarhouse Park, and the wide swings in pace are due primarily to the hills at the park--the very fast ones included downhill and the very slow ones included uphill. Even so, I was pretty inconsistent today.

Roughly 1-mile cooldown.
Average pace for intervals: 5:22/mi
I was surprised that my HR stayed as low as it did. That's a good sign. My legs were pretty tired, though, particularly on the intervals that included climbing. On my last few runs I've felt something a little weird in my right knee, mainly in the tendon on the outside but also just inside the patella. It's hard to explain but it's as though I feel the tendon moving around. No pain at all, but probably something to watch. |
