Recently, I’ve been riding strong until this past weekend. Did a 85 mile semi-hard ride on Saturday and felt ok. Afterwards, I kind of felt like I had ridden hard on a smoggy day and noticed that it a little difficult to take a deep breath. I took the next day off feeling more tired than usual. I did a 60 minute crit two days later. Felt ok until I needed to put out a full sprint effort. I just didn’t have the normal energy. Since then I’ve noticed that I still have some of that same sensation when trying to take a deep breath. It’s been 6 days since I first noticed this. I don’t have any persistent cough, just occasional, and more so if I intentionaly try to breathe deep. I’ve not ridden for the two days following the crit. Any thoughts or suggestions?
