I'm signed up for a spring marathon. This marathon offers "elite" runners bottle drops at four locations. I'm not elite. I'd be really happy with breaking 2:30, and I stand no chance of a top overall place. Can I have a friend pass me a drink bottle at one or two spots along the course? Does it matter if they do it at an aid station / drink table? I can't get enough down from paper cups alone, and I don't want to have to wear a hydration vest the whole race.
