It’s the first rule of cycle touring.
Pushing a laden bike over distance requires sustained effort. Taking a decision to change direction or to continue is rarely fruitful on an empty stomach. The brain needs many calories of energy to provide optimum solutions to mental and physical challenges.
On occasion I’ve made some questionable choices for lack of a plate of food.
Eat before you get hungry. Drink before you get thirsty. It’s the adventure travel self care mantra.
A simple rule to live by for survival on the road.
