Ideas for NY marathon care package?

[Geegee4]

DH Is headed to NYC in a few weeks and I wanted to put together some little surprises for his suitcase to let him know we’re behind him/support him. This is the first running event we haven’t been too...

So far I’m thinking: an inspiring book (ideas?), jelly babies, some kind of bath soak for after, clips for his race number, photo transfer for top (?), personalised Spotify playlist...

What sorts of things would you like to see? Would welcome any and all ideas!

Favorite cookies for after the race. New compression socks.
You can buy special paper for your printer that makes those temporary tattoos. Could your children design a tattoo that he could put on the back of his hand for inspiration?
Otherwise, a warm blanket from the charity shop so that he can stay warm at the start and then just leave it in the charity donation bin that they have at the start. Maybe buy a foil blanket for the same job but let the kids decorate it?
My friend lives her shoe charms but might be too girly!
