2027 Quivering Quads Trail Race

Now in its 26th edition, the Quivering Quads Trail Race is a quiet gem among Missouri trail half-marathons. The course winds through Cuivre River State Park, weaving along forested singletrack and rolling hills that keep runners engaged without overwhelming. With a median field of around 136 finishers, it’s an intimate affair — about 30% return year after year, and most runners come from just a handful of nearby states.

The race starts and finishes in the park’s wooded heart, where autumn leaves or spring greening set the tone. Aid stations are spaced well for a trail event, and the low-key vibe means you can focus on your own race without the crush of a big-city start. The finish offers simple post-race fare, and the camaraderie among the tight-knit group of participants is palpable. For trail runners seeking a no-frills, genuinely scenic half-marathon with a loyal following, this is a rewarding find.
