Capt'n Karl's Trail Series - Colorado Bend

Embark on an unforgettable nocturnal adventure at the Capt'n Karl's Trail Series - Colorado Bend on July 18, 2026, in San Saba, TX. This event, the third in the esteemed Capt'n Karl's Night Trail Run Series—the original and longest-running night trail series in the country—promises an exhilarating experience through the rugged and demanding landscapes of Colorado Bend State Park. Offering distances from a challenging 60K down to a fun 1-mile Youth Trail Run, alongside 30K, 20K, 10K, and 5K options, there's a distance for every trail runner seeking a unique test under the stars.

The course itself is a highlight, described as more reminiscent of the Western United States than Central Texas, boasting breathtaking cliffs, deep canyon lands, mysterious limestone caves, and serene natural springs, including amazing waterfalls and precious solitude. Runners should prepare for a rough terrain of boulders, large rocks, and spikes, requiring keen attention to footing. While not overly technical, the trails are deceptively tough, with some runners finding the 60K particularly challenging. Typical race day conditions in mid-July feature highs around 94F and lows around 72F, with a minimal 5% chance of precipitation, meaning even at night, runners should be prepared for heat and humidity.

Strategically placed, fully serviced aid stations will support runners on the 10K, 20K, 30K, and 60K courses, offering a wide array of fuel including cookies, PBJ sandwiches, fruits, pickles, various drinks, and electrolytes. The 5K distance, however, does not have on-course aid stations, so participants should carry sufficient hydration. Beginning in the late afternoon and evening, this night race offers a distinctive atmosphere, drawing both seasoned ultrarunners and families to one of Texas's hidden gems.
