I’m train approx 10-15 hours per week, which is having significant repercussions on my performance at work (sedentary, regular office hours + a bit) which relies on my mental capability. Does anyone have any suggestions as to what to try to prevent this brain fog? Or do I just not to accept this as part and parcel of being an endurance athlete?
Current routine involves commuting by bike, doing some intervals on my way in (typically sweetspot, nothing consumed during the workout) and then an easy ride home. I rarely end a session feeling glycogen depleted, but often feel empty/fatigued when starting sessions. I eat breakfast beforehand (e.g. two wholemeal bagels with peanut butter this morning) and have a small snack of greek yoghurt with honey after. I then eat lots throughout the rest of the day. I am sleeping ~7.5 hours per night, which is less than I would like but hard to change since it takes me a long time to fall asleep.
Thanks for your input.
