Does anyone know if you can sign your kids up for the kids races the day of the race, or do you have to do it before hand online?

According to the WDW marathon weekend website, registration for the family fun run and Pirates and Princess 5K are both closed.

The 5k is closed, but they have kids races on Friday and Saturday. Its done by age group. They even have a diaper dash for little ones.

I just checked the site and it said that you can register at the expo on January 4th, so I'll do that. Guess I should check the site before asking questions? lol.

Thanks anyway.
