Running 4:30 [5] 0.8 mi (5:38 / mi) +60m 4:34 / mi
8x hill repeats - up trail - started :46, then :37, then several near :31. Simply getting used to trail and how fast I could push w/o slipping was useful.
Also, the trail went uphill fairly steeply for first ~8 seconds, after which I could try to push just as hard, albeit on a flat section, thus really speeding up. I think this was really useful, mentally.
