A runDisney Limited Edition 10th anniversary Wine & Dine Half Marathon Weekend MagicBand is now available for purchase to all who have signed up for the race. Runners can purchase the band on the runDisney website by logging in and browsing to the merchandise section of the event. The marathon starts on October 31st, 2019. I am unsure how many of these bands are being made, or if this comes in a special box like Limited Editions usually do, but they are for sale for $34.99. If you can’t attend the race, you’ll have to eventually find these on eBay.
This MagicBand are not available from Disney online, but you can buy it from eBay by clicking this link which will take you right to the product listings (if any are available).
