Not sure what went wrong….

Ok, this year’s Firecracker 5K was actually 9 seconds FASTER than last year’s, but this year it was 69 F, 73 percent humidity as opposed to 82 F, 69 percent humidity last year.

Basically: 8:15 (too fast for me today), 9:01, 9:35 (26:52 at 3), 27:40.
Part of it was the blood donation 17 days ago and part of it was a good workout this past Monday. I like 3 days of rest between a good workout and a race, but this time I only got 2.

I started to walk just past 15 minutes or so; I had to walk 3 times in the last mile. I saw rivals going by but could do nothing about it….TODAY. :-)

Socially I took Tracy to the race; she finished in 39:20 which is 7 minutes slower than she was doing a decade ago. She wanted to leave early because she is a tennis fan and Wimbledon is on.

As far as the eye candy: cute spandex, transparent white shorts, VPL’s; it was all there. But today I was too slow to catch any of it. :-(

Back to actual running:

Blood donation seems to affect me in 3 ways:

1. Tempo pace is slower (latic acid accumulation accelerates at a slower pace)
2. VO2 max pace is way slower
3. It appears as if fatigue comes on more suddenly than normal.

What isn’t affected so much:
1. “hard” intervals with long recovery periods (e. g. 200’s)
2. weight lifting
3. Slow running and walking (say, 11 mpm running or 14 mpm walking)
4. Swimming, at least at the paces I swim.

This makes me want to take a human physiology course.

  1. When you give blood, you lose red cells whose primary function is to deliver oxygen to the tissues. This is most important when you are working very hard for prolonged periods (e.g. tempo pace or V02 max). Very hard effort (weight lifting, sprints) are mostly anaerobic so they aren’t effected much if at all. At low intensity (hiking) your heart rate can increase to offset the decrease.

    FWIW physiology was my least favorite med school class but I still liked it.

    • I knew some of that, but I didn’t realize that HR could go up for low intensity stuff to compensate. Thanks!
