I’m not sure yet if I’m at this stage but finding my usual routine of 5 years or so running so difficult. I should be at half marathon fitness with all my training but I’m not. I keep forcing myself out but it’s like trying to run through treacle and I have none of my previous energy. I can’t have lost my fitness but it honestly feels like it as my times are so much slower. I’m sad because I’m not getting my my endorphins and just feel like I’m crap.
Other symptoms are insomnia and low mood, brain fog maybe.
