running (treadmill) 1:45:00 [3] 12.45 mi (8:26 / mi)
As directed, I started this run as an easy med/long run with just a little incline on the treadmill. I added in the 6 quicker paced sections for 2:30, but I wasn't entirely sure what a 5 K pace was... so I ran these at just under a 7 min mile pace. I hope that was about right.
