Not sure if Sophie and Madigan's still has availability, but it let me right through to payment. I haven't been sent my runDisney registration yet, but imagine that takes awhile, but seem to be confirmed in there. I also had applied to HopeStory first and seemed to be waitlisted, so sought out the other. Only $1150 for the challenge, which also seems lower than most other options.
EDIT: Just looked, they are out of the Challenge, but still have all other races available if interested
Sophie and Madigan's Playground is excited to be an official charity group for the Disney Wine & Dine Half Marathon Weekend.
