About three weeks ago, while on vacation, I came down with a bad sinus infection. I get them frequently, so thought nothing of it. Thought I caught from my son's summer cold (he had just tested covid negative). But a day later, I started losing smell, again, no biggie since I often lose some smell with my regular sinus infections. I maintained my workout regiment at pace. Heart slightly elevated at same pace, I figured the humidity where I was because I live in the desert. Had one night of fever/chills, but was gone the next day. Otherwise just some fatigue after my workouts. I figured it was being on vacation, not having a care, whatever. Beside, I'm fully vaccinated (Pfiser).

Well when I got back, I talked with a co-worker who said they had all the same so got a test. Wouldn't you know. Tested positive. Right then my motivation was gone for a couple days. But since I was already almost 10 days in, I scheduled another test a few days later. Negative. Here's the thing. I'm fine at zone 2 or zone 4 working out. No issues. I was training at elevation to get back into the rhythym. But man, it seems like it takes longer to recover from VO2 max intervals. Wondering if this is mental or damage. I tried to do research, but like most covid stuff, the data is either old, out of date, or emerging data that isn't conclusive. Anybody experience this? Can't be from taking five days off. I do on occasion.
