The Onyx Race

Prepare for an unparalleled trail running experience at The Onyx Race, returning to the stunning McDowell Mountain Regional Park in Fort McDowell, AZ, on April 4, 2026. This isn't just another timed race; it's a unique, point-based challenge that redefines trail running for all skill levels. Runners will navigate five diverse out-and-back trails, ranging from 0.5 to 12 miles roundtrip, selecting their preferred routes to maximize points. Earn standard points by returning a flag from the turnaround, or push for 1.5 times the value by carrying a sandbag back to the start/finish. This innovative format allows for unlimited point combinations, offering a truly personalized race strategy within the 4-hour or 8-hour divisions.

The course itself provides incredible views of the mountainous desert landscape, featuring challenging terrain with enough climbing to keep things engaging, including rocky sections and some roots. Typical race day conditions in early April offer pleasant running weather, with historical highs around 84°F and lows around 51°F, and only a 2% chance of precipitation. As you conquer the desert trails, you'll find well-stocked aid stations and a dedicated Recovery Zone at the start/finish area, ensuring you can refuel and recharge before tackling your next strategic loop. The Onyx Race promises a fun, well-organized event that empowers every participant to craft their own adventure.
