I do all of my morning runs fasted. I sometimes get a similar feeling to what you’ve described, where suddenly I get an intense hunger feeling and even sometimes a brief moment of light headedness. It usually doesn’t last longer than a few seconds and doesn’t effect my energy levels or effort. I don’t take any calories for any runs shorter than 3 hours, and this always happens within the first 30 minutes of my run. In my case, I think it’s related to me starting too quickly before my aerobic system is fully online. It only happens maybe 1 out of 10 runs for me. How often are you experiencing this?
For at least 2+ years I have run 60-120mins in the early morning before breakfast without any issue – it’s just some good z1, sometimes z2 distance. For a long time I would eat banana on toast or porridge w/ peanut butter, banana etc. post run.
Well… since a few months ago I have started to get a really hungry feeling during the morning runs. Sometimes I might even feel dizzy for a split second! After a while I begrudgling started to eat something small like a Clif bar pre-run, but the feeling still occurs. I know I’m not under fueling for the day, as I eat probably more than my fair share of good quality food. Eating usually stops around 9pm, and I get up at 5:30 to train before work.
Has anyone else experienced this?
I’m 42 with a 15 year background mountian running. On average I train 20-25hrs per week, with 12-16 of that running. I eat a healthy european diet with a standard macro split – probably 50% carb and an even split with protein & fats.
