Congratulations to Raya for turning Purple, as well as sincere wishes for a quick recovery!
I was reminded of RunDisney recently. As many as 170,000 runners participate in RunDisney races each season. This past January, more than 30,000 runners took part in the WDW Marathon.
The "Dopey Challenge" requires runners to complete the four WDW races (the 5K, the 10K, the half marathon, and the full marathon) over the four-day WDW marathon weekend. That's 48.6 miles of running! 362 people have achieved "perfect Dopey" status, meaning that they have completed all four races every year for the eleven years since the Dopey challenge was introduced.
But you don't have to be an avid runner to participate in runDisney events. They require a minimum 16-minute-a-mile pace, which I know from experience means you can walk briskly a good part of the way!
