I keep a Cliff bar with me to munch on the way home from work when I know that there isn't time to eat properly before a ride. I think this is a hard time of the year since it is getting so hot so fast, and it's only been a few weeks since we were still wearing warmer clothes on the bike (at least for me).

Glad you were with others and you had someone to call. Glycogen depletion is awful, and you needed electrolytes as well. We lose stuff so fast in the heat...did you have a sports drink with you on the bike or just water? Water is good, don't get me wrong, but especially in the heat our electrolytes can get out of balance with just water which doesn't replace them. You probably already knew all this
