Mark your calendar for December 20, 2025! The Irving Frost Marathon is back to put some extra jingle in your stride. Whether you’re conquering the full marathon, running a half, or dashing a festive 5K, this is the race that wraps up your year with a bow. (And qualifies you for the Boston Marathon, if that’s what you’re after!) 

The course is fast and flat, winding through the scenic Las Colinas Urban Center and Campion Trail before sending you across the finish line at the Toyota Music Factory. Enjoy live music, high-energy crowds and a post-race celebration that’s as rewarding as the medal around your neck. 

And it’s not just about miles — it’s about meaning. Every step supports the Irving Schools Foundation, fueling scholarships and student programs that matter. Add in perks like race photos, swag and bragging rights, and you’ve got the ultimate holiday hustle. 

So go ahead — lace up, layer up and let’s frost the finish line together!
