39.3 miles? You’d have to be just downright GOOFY to run that! In celebration of our pal Goofy’s birthday today, we are sharing a few fun facts about runDisney’s 15th Anniversary Goofy’s Race & a Half Challenge as part of the 2020 Walt Disney World Marathon Weekend presented by Cigna.

The inaugural Goofy’s Race & a Half Challenge took place January 5-7, 2006 with roughly 3,000 participants. This year’s event, taking place January 11-1, 2020, will host over 10,000 participants.

Today, there are 78 “perfect” runners who have completed the challenge each year for the past 14 years! Each “perfect” will have run a total of 550.2 Goofy Challenge miles each, 42,915 miles combined, heading into the 2020 event.

Not sure just how many miles the event is? To complete the 39.3 miles of the Goofy Challenge, you would have to ride the distance of The Barnstormer Starring the Great Goofini roughly 270 times!
