I bonked in the middle of a 100km ride on a rail trail through farmer's fields. I thought I'd had enough food, since the same amount was sufficient for the initial trip out a few days earlier, but it wasn't. It was the return journey of my first big bike trip, and it was absolute hell after I bonked. I'd ride for twenty minutes, then lie on the ground for ten. When I was laying on the ground I'd be searching the vegetation for anything that looked vaguely edible.

Crazy how a glucose drop can sneak up and humble you so quickly!
