"Bonking" is quite a surprise to new riders; they generally have no idea until it happens to them the first time.
On a ride with George, I was starting to get wobbly and my legs were turning into noodles. We stopped at a local store where he instructed me to get a Coke and some peanuts. The sugar and salt straightened things out in short order and I was able to finish the ride.
If I am doing a long ride or riding somewhere without known stops I will pack a mini bottle of Coke or Pepsi in case of this emergency (along with at least 2 bottles of water and a snack).
Thanks for bringing up the topic!
