As a family of 5 signing up for a combination of the rebel challenge, 10K and 5K, which race should I start with to reduce the chances of someone missing out of what they want to run during regular registration? I was surprised when we signed up for the Avenger weekend that the 5K sold out before the half but I'm thinking that the Rebel Challenge will be the first to sell out, followed by the 10K and then the 5K. Does anyone know in what order and how fast the races sold out for Disneyland half/Dumbo double dare/10K/5K this year? I know it is guessing game but would appreciate other opinions.
