The CDC recommendations are posted on their website (I think you are in USA out west but am not certain). However, you need to go with how you feel and how you test and with appropriate care for others around you. We isolated for a week and masked up for a week after that and kept contact with others to absolute minimum for about three weeks. Anyone we were going to be close to while we might have been infectious (just a couple friends) we made aware of our status.
Definite bummer on your timing near an event.
I can share our recent experience, but talking to friends having symptoms and positive tests in the last 6-8 weeks (so the newer variants most likely), the extent and severity of symptoms, and recovery time after the main symptoms (fever and aches) break is anywhere from a few days to a few weeks.
Wife and I had mild to moderate cases. Never any danger of serious complications but we felt like absolute crap. She was infected in a location where people should know better. An employee came in sick and infected several co-workers and several clients. At least 15 people had symptoms and could be traced back to the individual of questionable judgement.
My spouse was obviously sick about two days after the exposure, but didn’t test positive for four days. She infected me and I tested positive as well. We didn’t need the tests as the symptoms were obvious. As an aside, neither of us used paxlovid. In discussion with our physician, felt that with our age and no health issues that we’d gut it out and avoid the possibility of “paxlovid rebound”.
Our courses of covid and recovery were similar. Early symptoms were scratchy throat, then the fever plus joint and muscle and head ache and worsening cough and nasal draining. Normal covid stuff. I ‘enjoyed’ an extra bonus of GI involvement plus nausea and food taste was significantly affected. About 14 days of weird taste then back to normal. I also had somewhat significant covid fatigue and brain fog. Was very tired and couldn’t concentrate on anything that required real thought. You wouldn’t have wanted me driving a truck or operating heavy machinery in that state!! Wife had the fatigue and some fog but was less severe.
It took both of us about 7-8 days post-symptoms to start feeling decent and then another 5-7 days to feel mostly normal. I would have been total crap trying to race during that two week period. I went for an easy ride when I started feeling better and had zero power and was gasping for breath on any effort. Am certain HR was elevated but didn’t measure it.
It is now three weeks since our first exposure and about a week since everything seemed decent again. Based on RPE and power, first few rides back were mediocre, but now after a week of decent riding everything is back where it was pre-covid.
Good luck with recovery and hope it goes well. Many folks have gotten used to living with Covid, but it’s no joke and having experienced it, will definitely take reasonable steps to not get it again.
