#RUNMARANA Dirt Dash at Wild Burro

The #RUNMARANA Dirt Dash at Wild Burro in Marana, Arizona on December 13, 2025 invites runners to explore the scenic trails of Tortolita Mountain Park for a half-marathon and six-mile race through breathtaking desert landscapes. The event takes place along the winding paths of Wild Burro Trailhead, where participants will navigate challenging elevation changes and picturesque views that stretch across the Arizona skyline.
On this crisp winter morning in December, runners will find themselves enveloped by the quiet majesty of Tortolita Mountain Park as they lace up their shoes for a day filled with adventure. The air carries an invigorating chill at dawn but warms gradually under clear skies or perhaps thin wisps of cloud that drift across the sun’s rays. As you set out, you’ll hear the distant crackle of wood in the campfire provided by On Your Left Fitness and Town of Marana Parks and Recreation; a welcoming beacon for those who will gather to cheer on runners as they complete their journey.
Now in its third year, this event has become an integral part of the local running community’s calendar. Each edition draws hundreds of participants eager to test themselves against both nature and time while supporting a meaningful cause: raising funds for environmental conservation efforts within Tortolita Mountain Park. Both veteran racers and newcomers alike appreciate the custom bibs and finisher medals awarded at the end, as well as unique challenges like outrunning the "Wild Burro" route director’s best times.
The half-marathon course begins with a relatively flat 2-mile run on Wild Burro Trail before veering into more rugged terrain. Participants face approximately nine miles of single-track trail characterized by moderate elevation changes and stunning vistas, culminating in another two-mile trek back along the washes to complete their journey over the finish line at Secret Springs Road. The six-mile race follows a similar path but is condensed within this distance, providing an intense yet shorter challenge for those looking to push themselves without committing to the longer half-marathon.
Weather forecasts predict conditions that will feel around 15°C with occasional winds blowing gently between peaks and valleys of hills. Expect firm and slightly soft trail surfaces underfoot due to recent dry spells in December. The chance of rain is minimal, leaving trails largely unobstructed but still rewarding those who brave the elements for an authentic desert experience.
Registration can be completed online until race day up until 7:45 a.m., costing $30 per person before that time and increasing to $40 on-site if space permits. Race-day registrants must use their personal devices rather than relying on paper forms at check-in stations near the start line located along Secret Springs Road in Marana, Arizona.
Participants should arrive prepared for early morning temperatures by bringing layers they can peel off as activity heats up bodies and spirits alike. The official start times are set for 8:00 a.m. sharp for half-marathoners followed shortly after at 8:15 a.m. for the six-mile dash, all kicking off from Campfire’s warming glow beside Wild Burro Trailhead.
