Welcome back to the Disney Parks Moms Panel, Shannon!
I'm excited to hear you will be participating in the 2016 Princess 5K. It's such a fun race.
There will not be race transportation from the theme parks to the ESPN Wide World of Sports for the runDisney Health & Fitness Expo. Luckily, your alternative is not a bad option at all, my suggestion is to walk from Disney's Hollywood Studios, or take a Friendship Ferry, to Disney's BoardWalk Resort. This resort is super close to Hollywood Studios and will be offering transportation to the Expo.
You will find this dedicated race transportation in front of the
Convention Center of Disney's BoardWalk Resort - you can see where to go by selecting the highlighted link of the map, the Convention Center is the building on the right side of the main entrance on the map.
I hope this helps, Shannon! Please let me know if you should have any additional questions as you continue planning and preparing. I am here to help.
