AustinBike Posted May 31, 2022 Share Posted May 31, 2022 This weekend I did 3 rides where I felt "out of it", basically when I rode with others I had difficulty keeping up. Even by myself I felt winded. Normally this happens when we get to summer with heat but this felt pretty harsh. Earlier in the week I donated blood. Does anyone know if that would have a big adverse impact on me and how long should I expect that to last? Quote Link to comment Share on other sites More sharing options...
AustinBike Posted May 31, 2022 Author Share Posted May 31, 2022 Using the google, I get this: https://pezcyclingnews.com/toolbox/how-blood-donation-affects-performance/ Looks like the long and short of it is that yes, there is a 4-6 week impact. I wonder how Texas heat plays into it. Quote Link to comment Share on other sites More sharing options...
hurronnicane Posted May 31, 2022 Share Posted May 31, 2022 It sounds like you did the opposite of blood doping. 1 Quote Link to comment Share on other sites More sharing options...

I wonder how Texas heat plays into it. I've never quite been in the same situation, but in the short term I've had a few experiences where I didn't properly hydrate after donation and I felt it bad. Almost passed-out just walking in an airconditioned mall once. I can imaging it being worse after riding given how much of a toll the heat takes on me. I remember reading an article about pro-athletes and it said that Hydration for them started days in advance of an event and recovery was the same. Add loosing a good amount of blood and it doesn't shock me. Quote Link to comment Share on other sites More sharing options...
AntonioGG Posted June 1, 2022 Share Posted June 1, 2022 Re-hydration has to be focused. Think lots of fluids and lots of salt/electrolytes else you just pee it all away. Personally, it takes me 2-3 days of focused re-hydration to fully recover after getting dehydrated. Quote Link to comment Share on other sites More sharing options...
June Bug Posted June 2, 2022 Share Posted June 2, 2022 Speaking of hydration, the Target store in the Arboretum/Gateway area (183 @ Great Hills Trail) has Nuun tablet (various flavors) Skratch in single packets and small bulk bags Honey Stinger waffles (gluten free and regular) and chews. It was somewhere in the sports/yoga section. 1 Quote Link to comment Share on other sites More sharing options...
AustinBike Posted June 29, 2022 Author Share Posted June 29, 2022 Gave blood about 4 weeks ago. For the first 2-3 weeks I went from averaging 11-12 MPH on urban rides to 10-11MPH urban and struggled on the trails. They said it could be 4 weeks before my oxygen was 100% back to normal. Got on the bike yesterday after 10+ days out of town and averaged ~11.5MPH. Very interested to see how I do on the trails this weekend. Clearly there was an impact.
