Does anyone here donate blood regularly? (other than falling off bike and sliding down tram lines)
and if so... how do you find it affects your riding? how long does it take for you to return to 100%?
I gave blood yesterday - bad timing since I had planned on going to Palace last night but there you go (last nights short ride left me feeling slightly dizzy, but I'd expected that and took it very easy).
Anyway, riding in this morning didn't feel too bad, took it reasonably easy and noticed that I was feeling (understandably) a bit low on power.
However, I really noticed it when I stopped though, with very bad pins and needles with toes and feet having a distinct lack of circulation going to them (left foot worst).
Perhaps I should skip a day after donating in future.
