About the Event

The Leaky Hourglass Ultra returns to Half Way, Missouri on August 29th, challenging runners with a unique Last Man Standing format that tests endurance over rolling hills.
Participants start the event at sunrise facing the challenge of completing each lap within increasingly tighter time constraints. The first loop offers 60 minutes for its completion; every subsequent lap loses one minute from this cutoff point until only one runner remains capable of finishing their assigned distance. This race takes place on a rural highway that runs through Half Way, where runners will encounter traffic and must adhere to road safety rules by running against it with headlamps after sunset.
The Leaky Hourglass Ultra has been an annual tradition since its inception in 2015, drawing approximately 300 participants each year. The event is not just a test of physical endurance but also a celebration of community and resilience, pushing runners to their limits while fostering camaraderie among competitors who share this challenging experience.
The course for the Leaky Hourglass Ultra winds through rural Missouri on a chip-sealed highway with notable elevation changes every lap, adding an element of unpredictability as each subsequent round becomes more demanding. Runners will find aid stations strategically placed at both turnaround points and the start/finish line to ensure they have access to Tailwind Endurance Fuel, water, snacks, and other essential items throughout their journey.
Weather conditions on race day in August are typically characterized by a firm yet slightly soft trail surface due to recent rainfall patterns. UV index levels tend to be high at 7.0, necessitating the use of sunscreen and protective clothing for runners to avoid sunburns during prolonged exposure under direct sunlight.
