As an Elite Athlete I'm training 20-30 hours a week. I got covid last year (triple vaxed) and it wiped me out for a good 6 months. It took me 3 weeks to be able to walk longer than a minute without needing to lay down for the rest of the day and sleep.
I have dealt with fatigue problems for 6 months and only just now, do I feel like I'm getting "back to normal".
The most frustrating thing is alot of people are dismissive of the symptoms and generally say, "Oh yeah, I get tired too" but fail to understand the severity of it as they haven't experienced it.
I have a fairly good understanding of my body and the associated symptoms of overtraining/fatigue in a heavy training cycle but covid fatigue was soemthing completely different.
