I think the drop in performance after giving blood is quite significant, since I have felt such an effect at least twice. I also think that the drop in performance only lasts a few days or a week, at least at my level of athleticism. I can’t speak for elite athletes, obviously.
My donations are only allowed every 56 days, which is the theoretical time required to replace the blood loss plus a large margin, I’m sure. I’ve been lucky since my donations have fortuitously been soon after a race rather than before. I know I could not and would not donate if I had a race less than two weeks after a donation.
At least that’s how I feel about it.
Tomorrow, I will be running the hilly trails in Devon’s North Saskatchewan River valley. And now, how about a couple of jokes? I really liked a T-shirt I saw on one of my friends who lives in Saskatchewan. It has a vertical rectangle drawn on it (which is the shape of the province’s borders) and the following text: “Saskatchewan. Hard to spell, easy to draw.
The other joke I have for you I got from Facebook and it goes as follows:
I went to the doctor yesterday and he asked me if I or many of my relatives suffered from insanity. I replied, no, we rather enjoy it.
Have a great run everyone!
