The adult stoker I ride with on longer rides seems to require almost no food, drink, or breaks... argh! "Want a cliff bar?" "No." "Need to fill up a bottle?" "No." "Want to stop up ahead and get off for a few minutes?" "Only if you need to."
We did our first century last month, and she was soooo proud of herself for drinking a whopping two bottles of watered-down gatorade plus one bottle of cytomax, and eating something at each of the four rest stops. I'm sure I had over a dozen bottles, and had some bars in between the supported stops.
...and, yes, she is pedaling.
