Join us on August 10, 2025 for the Rio Grande Half Marathon, New Mexico's premier half marathon. This race runs through the beautiful Albuquerque Bosque complete with views of the Rio Grande, beautiful Bosque cottonwood forest, mighty Sandia Mountains, and expansive New Mexico skies. The course is flat from start to finish so whether you're in search of a PR, looking for a fall marathon tune-up race, or just want to have fun, it’s the perfect race for you! If a half marathon isn't your thing, you can always participate in the One Medal 5k Run/Walk!
Our best-in-class technical finisher shirts and medals have a distinctly New Mexico flair that you will not find elsewhere. Post-race fun takes place at the Finish Line Fiesta where you’ll enjoy awesome live music, refreshing local craft beer from Canteen Brewhouse, and New Mexico breakfast burritos from Golden Pride.
Whether you're a local or are from out of state, the Rio Grande Half Marathon is the perfect race for you. Don’t miss out on the action and register today!

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
