As of this season, I am a NUUN/ZYM/GU electrolyte tablet convert. On hot, long rides I will carry 1 bottle of NUUN (or other type of tablet) and 1 bottle of plain water. I also carry a few extra tablets wrapped in foil in my bento box. I actually prefer the taste of the orange ZYM tablets over all the others, but NUUN is easier to find in my area. I don't like strongly flavored beverages while on the bike, so I tend to dilute mine a bit more. Aside from that, I generally always carry with me (but don't necessarily eat): 1 Luna or Lara bar, and a pack of Shot Bloks, Luna Moons, or Honey Stinger Chews (my personal fav!). On longer rides, I will sometimes also bring an Uncrustable (PB & Honey flavor). Depending on how I'm feeling, I may also share a banana (bought at a gas station) with my DH.
