I had three workouts within a 12-hour span last weekend. On Saturday evening I had a swim clinic with my tri club and followed it up by a 10k run. I had a light meal before going to bed and at 6am in the morning, did 3 hours on my bike. I felt strong in my workouts and didn't bonk, but looking back at my journal/HRM, I realized I expended 3,100 calories, while taking in only 1000 calories during the same time.
I refueled afterwards on carbs/protein and got some calories back in, but haven't felt right since. Other than an extreme craving for chocolate cake (which is unusual since I don't eat sweets and haven't had choc cake in years) I seem to have lost my appetite. I am also feeling tired and lethargic, and my resting heart rate seems to be elevated.
Not sure if this is an after effect of my workouts, or if my body is fighting off a virus (which it feels like). Anyone else experience this?
