About this race

Join us for one of the most fun and unpredictable races of the year—the Sandbagger 8K!

📍 Location: McBaine Katy Trailhead – Mile Marker 169.5
📏 Distance: Certified 8K (out-and-back) – MO21022MU

How it works:
Before the race, you’ll predict your finishing time. Runners start in staggered order based on those predictions. In theory, everyone finishes together—but this race tends to attract some very good liars 😉. The first runner to cross the finish line wins the race, earns bragging rights, and gets to add something to the 3-foot-tall traveling trophy which they keep until next year.
