Ready to push yourself to the limit? Join 175 runners for an intense 24-hour endurance event at Balloon Fiesta Park on May 30-31, where you'll complete ten back-to-back 5Ks starting at 8 am with 2.5 hours between each race—you'll need to finish one before the next begins, so bring a headlamp for the nighttime miles! You can catch some sleep between races by camping in the grass field or resting in your car, and you'll have access to four full meals plus snacks and drinks throughout the day and night. Top it all off, finishers receive a unique coffin award, a commemorative shirt, race swag, and serious bragging rights for conquering this mental and physical challenge.
