Hi Amanda!
Your best bet is to go to the
Tinkerbell Half Marathon website. Click on the "RUNNER INFO" tab, and then "Official Race Program". You can download this program. On page 35 is detailed instructions for Driving Directions and also a list of hotels that you can catch the shuttle from (that are non-Disney). This booklet will also be available in printed form at the expo. (you may want to print out just that page for reference to take with you as well)
You will be able to sign up for Runner Tracking about a week before the race. There will be a link to it on the
Tinkerbell Half Website. It will be under the tab "SPECTATORS". When you sign up for it, you can have it send runner alerts to text messages, emails, Facebook, and Twitter. You will search by runner name and go from there! Keep checking back on the website for the link. If you can't find it within a week of your race, please let me know!
Let me know if you have any other questions and good luck at the Tinkerbell Half Marathon!
