Embark on an unforgettable trail running adventure at FlatRock, Kansas's first and oldest trail ultra, held on September 26, 2026, in Independence. Known for its challenging and technical terrain, this iconic race offers distances for every level of trail runner: a grueling 50K, a demanding 25K, a spirited 12K, and an accessible 5K. Runners can expect typical race day conditions to include comfortable highs around 79F and lows around 56F, with a modest 13% chance of precipitation.
The FlatRock course unfolds along the beautiful Elk River Hiking Trail, a double out-and-back route that promises a unique Kansas landscape. You'll navigate mostly single-track paths winding through striking limestone bluffs, intricate rock formations, and picturesque vistas. While there are "no long hills," prepare for repetitive small elevation changes and a very rocky surface that demands constant attention, with the 50K boasting an estimated 3,000 feet of elevation gain and loss. Aid stations are strategically placed throughout the course: the 50K features seven stations, with five fully-stocked providing water, electrolyte drinks, soup, sandwiches, and other snacks, alongside two water-only stops. The 25K has three aid stations, two of which are fully stocked, while the 12K offers one fully-stocked station, and the 5K is self-supported. Carrying your own water is mandatory for all distances.
FlatRock is more than just a race; it's an experience steeped in lore, with epic years like the 2017 flood adding to its legendary status. Runners consistently praise its challenging nature, noting that the "rocks start to grow" as fatigue sets in. For those seeking an ultimate test, completing the 50K ten consecutive times earns you a coveted induction into the "FlatRock Hall of Pain," a testament to the enduring spirit of this "tough and challenging" course. The race headquarters at the Outlet Channel Group Shelter on the north side of the Elk City Lake dam serves as both the start/finish line and a welcoming hub, offering a pre-race spaghetti dinner for participants.
