Must go running with Debra! Sounds like ultra marathon approach almost, or my Christmas shopping.

Yes, to jelly babies, jelly beans. Usually 1-2 sports drinks will do me for up to 26 miles training.
Depends on what race you're training for...do they do provide sports drinks, gels ?
Liverpool weren't going to have gels or sports drinks, just water till late on, then did...
Had already started using clif blok shots which I find a lot easier to stomach than gels... Little gel cubes, in a pack of 6 for 2 quid. 3 cubes = 1 gel, but you can take smaller amounts so much less waste.
I've used zero , it's good for rehydrating but useless for long runs since no carbs... But a hot day handy to have 1-2 if sweat & heat a problem.
So fine for gym classes, and recovery to take in salts but not much else.
