Tucson Shamrock Half Marathon

Get ready to embrace the spirit of St. Patrick's Day at the Tucson Shamrock Half Marathon, 10K, and 5K on March 8, 2026, in sunny Tucson, Arizona. This popular early-season race, now a cherished annual tradition, promises a festive atmosphere and a rewarding experience for runners of all levels. Starting and finishing conveniently at Brandi Fenton Memorial Park, the course takes participants along dedicated paved trails, offering scenic views of the desert park and some welcome tree cover. Runners can expect a mostly flat course with gentle undulations, making it ideal for those chasing a personal best or simply enjoying a leisurely run.

Participants in the Half Marathon, 10K, and 5K will find ample support throughout their journey. The half marathon course boasts nine aid stations, providing water and Gatorade, with GU Gels available at miles 5.1 and 8.1. Restrooms are also conveniently located on the half marathon route at miles 3.11, 5.1, 8.1, and 10. Adding a unique twist, 5K runners can partake in the "Chase the Leprechaun" challenge, earning a prize if they manage to pass the elusive character before crossing the finish line.

As you cross the finish line, celebrate your achievement with a custom finisher's medal, a choice of a custom tech shirt, and a delightful post-race "Athlete's Brunch" featuring fruit, granola bars, water, and Gatorade. Typical race day conditions in March offer pleasant running weather, with highs around 75°F and lows around 47°F, and a low 2% chance of precipitation. This community-focused event is also welcoming to strollers and leashed pets, ensuring an inclusive experience for everyone (though they start at the back of the coral).
