Great Sandbagger 8K
The Great Sandbagger 8K is a certified 8K running race held at the McBaine Katy Trailhead, Mile Marker 169.5, in McBaine, Missouri. The course is an out and back and carries certification code MO21022MU. The event date is August 1, 2026.
Before the start, each runner predicts a finishing time. Runners begin in staggered order based on those predictions so that, in theory, many competitors finish together. The first person to cross the finish line wins and adds an item to a three foot tall traveling trophy that is retained until the following year.
Registration is online only through RunSignUp; on-site or race day registration is not available. Registration opens January 20, 2026 and closes July 31, 2026. Entry is free for Columbia Track Club members; non members pay a $10.00 entry fee.
The event description notes that it attracts a range of performances due to the prediction-based start order. The format emphasizes predicted finish times and the race outcome being determined by who physically crosses the finish line first rather than by chip time.
