Run 8 - full throttle in train-speak

Treadmill - 1% slope

4 miles - 35:44

A new personal best. Just a shade under 9 minutes per mile over that distance. I didn't give it much of a kick at the end so I could probably do it faster.

Then I slowed the treadmill down a bit and ran another half miles, finishing 4.5 miles in 39:33. That's about one-third of the way to a half-marathon!
