Notes
Wimped out and ran in the field house instead of in the -27 wind chill.
Did the first 10k in about 45 minutes, then did 3x1000m @ 4:00 with 1000m rest in between, then ended with 4x350m at the end of each km.
The info on the wall says it's 6 laps for 1k, I'm 98% sure that's the inside lap based on my pacing, I think the outside lap is 200m.
