openers for tomorrow's CX race. My basement got in the low 60's in the first time in forever and it makes a big difference vs 70+ degrees, I feel. I did 2x3min @ 100% (310) and I wasn't really hitting threshold HR (164 or 165) until the end, whereas the same workout last week had me at 169bpm at the end of the 2nd interval. I'd been going through a bit of a crisis of confidence with my training zones as of late, so hopefully the cooler fall weather approaching will help me question myself a little less!
