I'm beginning to question my HR monitor numbers. The last few runs, the HR has read unusually low given the speeds I was doing. This run is a perfect example of that, as I ran repeats on the treadmill on 2/24, 3/3, 3/10, & 3/24 all with avg HR in the mid to upper 160's...and now I blow this one out at 156?

The only thing that makes me think that avg *might* be legitimate is that this was a "taper" repeat session, with super short intervals (.25) as opposed to the monster 1m & up intervals I've been doing in the past.

Oh well, I'll just choose to look at it that way and let it give me a good confidence boost here in raceweek.
