Hermit Club...WOW... what a hard lesson to learn... the HARD way!
I think every single person here has done what you did... but we were fortunate not to injure ourselves because of it.
For me, I have learned that I need to EAT on a ride longer than 30 miles and for ANY ride I do, I have to eat at least 600-800 calories for breakfast.
Being hungry with a growling tummy... on mile 35 of a 50 mile ride is downright miserable. Not to mention, it's near impossible to move forward when you are that hungry.
I hope you heal soon and are back to biking when you are cleared by your Dr.
