yea, I'll have to monitor this a bit more closely to see a pattern. I could be a bit anemic, I don't take iron but have had good iron levels whenever this has been checked, even through pregnancy. But I haven't trained consistently this hard before, at least not endurance stuff.
Not that I'm really training that hard, but I'm training a lot more with other people, so I probably try harder to keep up instead of just slacking off if I have a bad day, and notice the bad days more clearly since I have someone to compare myself with.
Can't think of any other obvious factors. I'd been mostly off my bike for a week, in the mountains doing fieldwork and skiing. Fairly hard physical work (shoveling snow, toting heavy stuff and galumphing uphill) but with a few good rest days after with just a couple of easy commutes, so in theory I should have been mentally and physically raring to go. Ah well.
Have to get one of those wristbands
