I am fairly new to serious road cycling, and I have a question regarding training after donating whole blood. I have been using a stationary trainer for the first time over the past few weeks, and everything seems to be going well. I am able to maintain an average HR of around 175-178 for an hour and a half without feeling bad (31 years old, 230 lbs). Not new to exercise (running, lifting, etc.)
I regularly donate whole blood, and was wondering if I should lay off the trainer for a few days after, or just get on and let my body tell me. Something tells me that those kinds of heart rates might not be good for me right away. One of my secondary goals is weight loss, so I'd like to consistently stay on the bike. My main cycling goal is becoming stronger on the bike because I enjoy it, so if hitting it hard after donations would set me back I'd rather not do that.
During the spring/summer/fall I plan on at least 100 miles a week, so I will probably give up the donating until winter. However, I want to keep donating during the winter and was wondering what some of your experiences might have been. Thanks in advance.
