Get ready to conquer the "Grand Canyon of Texas" at the 3 Chaparrals 3/6 Hour Trail Run on March 28, 2026, in Canyon, TX. This unique fixed-time endurance event challenges runners to complete as many 4-mile loops as possible within their chosen 3-hour or 6-hour duration, with a 6-hour 3-person relay also available. The race honors Red Spicer, Bob Givens, and Tom Lowry, pioneers of Palo Duro Canyon State Park, setting a historic tone for this relatively new event, which was inaugurated in 2025.

The course itself, the Kiowa/Comanche Loop, is a 4-mile journey through the stunning and rugged landscape of Palo Duro Canyon State Park. Runners can expect a technical trail with portions featuring sandy dirt, jagged rock steps, and compacted gravel, demanding attention and resolve. With an elevation gain of 261 feet per loop, the course offers a physical challenge complemented by breathtaking views of the second-largest canyon in the United States, showcasing vibrant red and ochre rock formations. The start and finish line at the Mack Dick Pavilion serves as the central hub for the race.

A single, well-stocked aid station is conveniently located at the start/finish area, providing water, electrolyte drink mix, Coke, ginger ale, pickle juice, gels, and a variety of sweet and salty snacks like PB&J, pretzels, and fruit. Remember to bring your own hydration vessel, as this is a cup-less race. Typical race day conditions in late March include comfortable highs around 71F and cool lows near 38F, with a minimal 4% chance of precipitation, creating ideal trail running weather.
