For one hour or less rides, tropical fruit Cytomax mixed with pink lemonade Crystal Lite for a yummy tart drink. Longer rides, I use Hammer Gel, either raspberry or banana. Endurolyte capsules when it's hot.
I'm going to experiment with other drink mixes to augment the gel on long rides. My stomach is OK with things like Nectar and Mojo bars, fig newtons, Pay Days, cantaloupe and PBJs but sometimes my tastebuds rebel and I can't eat too many peanuts anyway. I never hold the rest stop food selection against ride organizers because I never know what I want until I'm standing there. How should they?
On the other hand, I can be highly critical of the food at the end.
