Embark on an unforgettable trail adventure at the Six-O Trail Run, set for September 5, 2026, in the scenic expanses of Cleburne, Texas. This unique event takes place on the private 1600-acre Six-O Ranch, a working cattle ranch that typically remains closed to the public, offering runners an exclusive opportunity to explore over 20 miles of diverse trails. Choose your challenge from a 6-mile loop, Half Marathon, Marathon, or the demanding 50K ultra, each winding through a captivating blend of single track, wide-open dirt ranch roads, and even a few thrilling water crossings.

The Six-O Trail Run course promises a dynamic experience with steadily rolling hills and "some hills" throughout. The Half Marathon, for instance, features approximately 1174 feet of elevation gain and descent per 13.3-mile loop, while 50K runners will tackle around 1317 feet of elevation per 15.6-mile loop. Expect well-marked trails with confidence markers every quarter mile, though a keen eye is always recommended, as the resident cattle occasionally rearrange course markings. Runners consistently praise the race for its beautiful scenery, informal atmosphere, and strong sense of community.

Prepare for typical Texas summer conditions, with historical race day highs around 92°F and lows near 69°F, and a slight 10% chance of precipitation. Being a cupless race, all participants are required to carry a hydration device to stay fueled. Aid stations are strategically placed to support all distances, with the 50K and Marathon courses featuring multiple aid stations per loop, ensuring runners have access to necessary refreshments. Primitive camping and parking are available on-site the night before the race, fostering a friendly, communal experience right at the start/finish line.
