During endurance runs, many athletes experience intense hunger pangs—legs turning to jelly, struggling to push forward, and even slight vision blur. As a seasoned running coach with years guiding marathoners, I've seen this derail countless training sessions.
What exactly is a hunger knock?
Untrained runners are especially prone to sudden hunger knocks, a clear sign your body has shifted to fat burning. While that sounds efficient, it actually means you've depleted glycogen stores—the fuel your muscles and liver convert from carbs into glucose. Blood sugar plummets, triggering ravenous hunger and a sharp energy crash.
How to prevent hunger pangs: Fuel up with a light, carb-rich snack over an hour before your run. Opt for easily digestible options like grains, pasta, or fruit to maintain steady energy.
