I went running with her yesterday and finally got some information.
I told her to run for 20 minutes on Monday — she said she ran for half an hour (Sounds like a real runner).
She used to do Night Moves, said she even won her age group sometimes. Even better. I’m far less worried now. Don’t know how fast she’ll be, but she sounds like someone who will be able to train to finish in the time we’ve got.
