Potosi, United States of America · Saturday 16 May 2026
Potosi, in the heart of the Missouri Ozarks, offers runners a chance to experience the region's mining heritage and natural beauty in one outing. The town sits in landscape shaped by centuries of lead extraction, and the surrounding area carries that industrial history alongside genuine small-town charm. For a runner, this means a course that moves through genuine community rather than manufactured race scenery, with the kind of genuine local support that makes a marathon feel like an event rather than a staged performance. The Berryman Marathon course itself reflects the terrain of the region, offering a flat to gently rolling route that won't punish your legs with surprise elevation but keeps things interesting enough that you're not running in a complete vacuum. A truly flat course can be deceptively tough on the mind, but the gentle undulations here break up the rhythm enough to maintain engagement without requiring the kind of mental fortitude needed for sustained climbing. The elevation profile suggests you'll spend the race at roughly the same altitude throughout, which is a practical advantage for pacing and breathing. Running in May puts you in decent timing for the region. You'll likely avoid the oppressive heat and humidity that defines a Midwest summer, though you should still prepare for variable conditions typical of spring running. The course takes you through and around Potosi, letting you see how a working town actually functions rather than just passing through the polished downtown core. This is a marathon for runners who appreciate straightforward courses and genuine local hospitality over elaborate production values.
