Unspecified 1:00:00 [3] 8.1 mi (7:24 / mi)
Okay, I went a little off plan today. I had the choice of a couple of easy runs from 45:00 - 1:00:00. Instead I started at 7.1 MPH (8:27 pace) and every 3:00 I increased the speed by 0.1 MPH for an entire hour which means I finished the run at 9.0 MPH (6:40 pace).
I had originally thought I would just increase the speed this way for the first 15:00, or until I got to a faster yet comfortable pace, then maybe out to 45:00 and call it quits. But once started I just took it out to an hour.
Maybe one day when I have lots of time I'll try doing this workout again but walk it back down from 9.0 to 7.1 for a 2 hour run.
