I was going to say the same thing - the checkpoint/bag drop is at mile
62, so that'll be the last chance for a water refill. I'm planning to
use a camelback, but i'll probably have a small backup bottle of water
in the bag anyway. I don't know what else i'll have in there though,
maybe some food, that's about it. Depending on the weather during the
day, it will be nice to have the option of dropping some clothes
there.
