I've recently had a sinus infection and bronchitis. I was sick as a dog for a week with fever, etc and now I'm on amoxicillan and finally feeling good enough to work out like I used to.
I've been doing interval cardio training all year, not so much distance running as our season up here for running outside is just beginning. Also, I took a good two weeks off of training to get well again.
So today was the first time in gosh, 6-8 weeks that I attempted a longer run. My goal was a simple 2 miles in twenty minutes.
Mind you, I run a 5K in 27 min. usually.
Holy crud, I had a hard time finishing at goal! I made it, yes, but with the nausea I feel at the end of a 5K competition!!
What is going on?
I'm thinking lower oxygen uptake from residual mucus in the lungs? Or, still in recovery stage of illness leaving me energy depleted? Or the 6-8 weeks not focusing on cardio has really gotten me out of shape?
Any thoughts from the medical professional peeps?
