This weekend happens to be the same weekend that Hong Kong
Disneyland has held their running event for the past two years and is a week before Disneyland Paris RunDisney weekend. This event, as well as the last two Hong Kong Disneyland events, are organized with the local park partnering with the main local running organization.
At the 25th WDW RunDisney legacy celebration it was stated that they plan to have RunDisney events at all parks around the world. I wonder if Hong Kong will be happening this year...and how about Tokyo?
