I was notified late last night that the charity I wanted to run the Marathon for was going live with registrations sometime today. They went live slightly before noon for sign-up, as all those who were interested were emailed as it went live.
runDisney still doesn't have any charities listed or links to any of the charities on their website.
When I registered for the Marathon their count showed 42 bibs for each race during each race weekend (excluding Spring surprise, which they will have bibs at a later time).
So yeah, I'm signed up for the Marathon and hopefully come Tuesday I'll be able to sign up for the 10k too!
