Day 41 - Low Blood Blood Level

Today was destined to be slow for two reasons. First, my right knee is pretty sore. I can't tell for sure if it is "get it warmed up and it will be fine and the pain will go away tomorrow" sore, or "keep pushing and you will regret it" sore. My inclination is to take it easy.

Second, I donated blood at 2:30pm, and didn't have a chance to run before that. So my run is two hours after losing a pint. I am beyond low blood sugar level and into low blood blood level. Ten years ago I would have sneaked out of the refreshment area early and completely ignored the admonition to not exercise at all for 24 hours or strenuously for 72 hours. At this point in my life, the possibility of passing out on the bike trail seems less abstract than it used to, and doing that just two hours after donating and being told not to for exactly that reason would be pretty embarrassing.

So I ate lots of cookies, drank a lot of fluids, and jogged my 3.2 mile loop very, very slowly, taking about 33 minutes, and I did not get dizzy, fall down, or lose consciousness at any point. My knee didn't feel any worse jogging than it did sitting at my desk, which was a relief. But I'll probably continue to take it really easy on the running for the next couple of days.
