The North Texas Ultra, scheduled for Saturday, February 7, 2026, at Fort Richardson State Park in Jacksboro, offers runners an unparalleled ultra-marathon experience across various distances from the accessible 5K to the challenging 100K. Nestled along the wide and soft gravel Trailway within a historic park setting, this event features relatively flat terrain with only 550 feet of elevation gain per 15.5-mile loop, making it an ideal course for achieving personal bests. Early morning start times begin at 6:00 AM for those tackling the full 100K distance, ensuring runners have ample daylight to navigate through this scenic and fast course. A key event in the Texas Ultra Series, North Texas Ultra rewards participants with collectible finisher medals that form a Lone Star design when accumulated over multiple races throughout the series. Additionally, top performers earn qualification for the prestigious Big Texas Ultra Championship. Organized by Texas Outlaw Running, the race offers exceptional value and quality amenities including custom-designed shirts, 100K buckles, and a fully supported environment with a friendly atmosphere. Whether you're an elite runner aiming to break records on the full distance or a newcomer looking for the challenge of the RUCK division at 25K, this winter event is meticulously planned to cater to all levels while highlighting the rich trail running culture in Texas. The North Texas Ultra promises not just a race but an immersive experience that celebrates both individual achievement and community spirit amidst one of Texas's most historic and picturesque landscapes.
