Leaky Hourglass Ultra

The Leaky Hourglass Ultra is a unique Last Man Standing running event scheduled for August 30, 2025, in Half Way, Missouri. Participants will tackle a 4.167-mile out-and-back course on a chip-sealed rural highway with rolling hills and an elevation gain of approximately 250 feet per lap. The challenge intensifies as each lap reduces the time limit by one minute, creating a competitive atmosphere until only one runner remains.

The event features aid stations with various refreshments and allows for primitive camping nearby. Registration closes on August 23, 2025, and bib transfers are permitted until August 3, 2024. Visit the organization's website for the most recent information.
