Embark on an unforgettable trail running adventure at the Hawk Hundred, hosted by the dedicated Lawrence Trail Hawks in Lawrence, KS, on September 12, 2026. This challenging event offers distances for every ultra-aspirant, including 100-mile, 50-mile, and Marathon options, all centered around a demanding 25-mile loop through the technical, rolling trails of Clinton State Park. Marathon participants will tackle an additional 1.2 miles on the Nature Center Trail before joining the main loop.

Runners can expect a course that is approximately 95% un-paved, featuring rocky sections with roots and ruts, and significant elevation changes, including a 1.1-mile out-and-back to Sanders Mound and two ascents of Bunker Hill within the 2.5-mile Goodwin Loop. One review notes considerable elevation gain, around 2100 feet per 25-mile loop, making consistent running difficult and emphasizing a rewarding challenge over personal records. Typical race day conditions in mid-September include highs around 84°F and lows around 58°F, with a 13% chance of precipitation, providing a varied experience.

The Hawk Hundred is renowned for its exceptional camaraderie and support, boasting three fully-staffed aid stations equipped with standard ultra-runner fare, including Tailwind and Honey Stinger products, and even hot food and soups for overnight runners, with one famous stop rumored to serve bacon. Aid stations at Lands End (4.5 and 18.5 miles) and West Park Road (10.5 and 13 miles) strategically break up the 25-mile loop, with West Park Road and the Start/Finish line offering crew access. Finishers are celebrated with unique awards: a custom buckle for 100-milers (with a special design for sub-24-hour finishers), handcrafted mugs for 50-milers, and bespoke medals for marathoners, all crafted by Matty Mullins. This race, a cherished part of the Kansas Grand Slam of Ultra Running and the Flyover Slam, guarantees a tough, fun, and memorable trail experience from start to finish at Clinton State Park.
