Running 24hrs after blood donation

Probably not advisable! I have just completed W4R3 just 24hrs after giving blood. I have never had any ill-effects after giving blood so I thought I'd give it a go. Well, the final run was a major struggle... it was more like a fast shuffle than a run! But I pushed myself through it and made it somehow. Felt absolutely shattered afterwards (far more than W4R1 or W4R2) and I suspect I will be a bit sore tomorrow.

I think I'll give it at least 2 days after donation next time!

  • When you give blood, you lose about 13% of your red blood cells - kind of like reverse blood doping! The white cells and platelets are replaced in a day or so, but it takes weeks to replenish the red cells!

  • Interesting. I went to give blood last week after a run, and they wouldn't take it. I failed the haemoglobin tests x2 by some margin, and reading about it at home later, it said exercise can be a contributor to low haemoglobin. I'm getting a proper test at docs next week, but wonder if the run prior to trying to donate affected it, just as the run after did for you?

    Anyway, hope your next run goes well, and I'll remember to avoid running near a donation in future too!

  • Well done you will really feel the beneficent run!

  • Or even the benefit next run!

    Good to know I will bear this in mind next time I donate.

  • Did you drink enough afterwards? Donating can make you dehydrated...maybe it was just one of those runs...

  • I certainly tried to, both before and after the donation. I guess it could have also be the fact that I ate about 2hrs before the run... I normally run first thing in the morning on just a cup of tea. Anyway, W5R1 tomorrow morning... onwards!!!
