Friday, I gave a 'double-red' blood donation - my first in a number of years and I'd never even heard of the 'double' before Friday.
I'm training with the advanced 10K team, and yesterdays (Saturday) run was awful for me. Had to walk a number of times, battled the whole way.
Today, on the treadmill, again I was exhausted after a few miles, my heart rate was also way higher.
Does anyone have experiences with running after blood donation? When will things improve? Should I take a break for a week, or keep going?
This blog, shows that many people have had a similar experience.
