Take the option to add on an extra 0.3-miles onto your race at the Center of the Universe Detour for the “World’s Shortest Ultramarathon,” or head straight to the finish at Guthrie Green and enjoy the post-race party! Participants who stand at the center of the brick circle (the Center of the Universe) and talk or shout will hear themselves echo, but others outside the circle will not hear the echo. Crazy! In true Route 66 fashion, you’ll earn a Michelob Ultra beer as your reward and receive a special commemorative coin! The Center of the Universe is also an official Red Bull Zone, and people dressed in costumes will run the detour with you!
