In reply to TheDrunkenBakers:
I got some relatively professional advice on this last feb, I was pretty fit, a month out from several big events and had covid.
Advice I was given said do nothing other than walk for 2 weeks after last covid symptoms disappear, then build up weekly 30,50,70,85% of previous training level, throwing in a recovery week if you feel the need. From first having covid it could easily be 10-12weeks before normality returns. For some even longer.
You might be vaccinated, but your body has been and still is working hard fitting the infection, repairing cellular damage etc.. this holding back on training is likely tough psychologically, but play the long game.
