Hello from NYC, it’s the NYC marathon this weekend!

My friends and I live around Mile 18 of the route and we always go down to cheer the runners on. Last year we discussed that we should offer something beyond cheers and shouts.

One of my friends was thinking about pooling our money together and buying some snacks and cookies and just having a big “snacks for runners” sign. Would this work? Would this be helpful? What kind of snacks work best? (ideally something available at Costco)

None of us are runners beyond the occasional turkey trot so we have no idea. So turning to r/running hoping for some feedback before we buy $500 of snacks that nobody wants.
