– If I’m bonking on a long route and I only have one gel to last me several hours, should I ration it, or just eat it now and avoid any potential sticky mess?
Since the brain need glucose save the gel for technically demanding sections or when important decisions need to be made.
Take more gels with you.
This is advice of the greatest kind – seems obvious after reading it, but I never thought about it this way (maybe I need to eat more..). A situation where you’ve run out of food for long enough to bonk is almost certainly one in which things are decisively not going to plan, and brain performance is probably more valuable than any other kind. I’ll definitely be thinking about maintaining a last reserve of brain food as an essential part of the things-went-wrong strategy.
