Hi Taylor!
Thank you for bringing your question to the Disney Parks Moms Panel!
How exciting for you and your mom! I just ran the Doctor Strange 10K with my son and it was so much fun. You guys will make memories that last a lifetime.
The ChEAR Squad includes different packages that are available for purchase during half marathons and marathons. Spectators do not have to purchase them, but they offer things like preferred viewing areas, private restrooms, etc.
For the 5K race, there won't be any ChEAR Squad packages (unless
runDisney really decides to mix things up on me). Your family members are definitely welcome (and encouraged) to come and cheer you on!
Please let me know if you have any other questions before your big race!
