Notes
3 x 2 miles steady at @ 6:18/mi. on two different treadmills. I reluctantly ran on treadmills because of cold, rainy weather. My warm up and first interval were on one treadmill, on which 6:18 pace felt fast. It made my stomach hurt, so during my planned 4 minute break I visited the bathroom. When I returned, all the treadmills were full. I ended up waiting 13 minutes before starting my second interval on a different treadmill, on which 6:18 pace felt slower. I didn't have much trouble either with that interval or, after a four minute break, the third one. My guess is that the first treadmill was calibrated too fast and the second one too slow, but maybe the second one was closer actual 6:18 pace. It was quite hot in there. No time for exercises afterwards.
