you learned a couple of the key lessons in longer rides:
1) know how your body needs to refuel. You found out the hard way. Bananas are your friend
2) Stop at the aid stations. Having too much water on board is better than not enough
3) carry a pump! Weight? The time you spent futzing around is about the time not having that weight saved you
Congrats on your first century! And kudos to the wife and kids for supporting you, it's a big deal!
