We found a viewing spot at Mile 11, right before a hill, and listened as one enthusiastic spectator cheered the racers with "You're waaaay past half way."
"I heard you before," some of them said, smiling and laughing and ever so slightly picking up their pace.
Finally, we saw Claire, Number 658. Though she's only been running for a few months, she was in fine form, bouncing along as if the rain and the run weren't fazing her. We cheered, she gave us a quick hug and ran off to tackle the last two miles.
Funny thing, she said later — the spot we picked to stand was right where she needed us most.
