I did 5 weeks of ss training and got sick during the recovery week. Heavy flu with diarrhea. 8 days off the bike and I was feeling it again. I did two easy ride in zone 2 about 7 hours over two days.
The slow stuff felt alright to good even. But I had nothing extra, tempo felt like threshold. 180-210 watts for 3 hours felt easy but doing 240-260 was really hard for 5 minutes.
Does anyone know what is going one or how long it will take to get back to normal form?
