Run Interval

WOD: 8X400m at best 5k pace, 3 minutes rest inbetween. I rested just over 2 minutes in between (had to get somewhere). My best 5k pace this training season so far was 8:04 min/mile, so I set the treadmill to 7.5 speed. Ended up at 7.6 for the last 4 and even at 7:53 min/mile it felt sort of slow - strange. Results:
1:41 (watch problems only .20 dist), rest were all w/in .01 of .25 (up or down) Times were: 2:05, 2:13, 2:14, 1:59, 2:06, 2:01, 2:03

I must say the treadmill start up time and my watch not registering a lap when I press the button were all frustrating on these short sprints. Would have liked to have done this outside, but did not work out today.
