I must say that, although uncomfortable with the resulting amount of garbage, one of the perks from half-marathon races that I enjoy is not having to wear my fuel belt. Of course these are events that I trust are well organized.

It's like going out without a jacket on the first day that's warm enough in the spring. Liberating!

(At a recent race where I was, they had biodegradable cups, but nonetheless it's a lot of resources wasted.)
