The Royal Gorge Groove is a high-altitude endurance event scheduled for Saturday, April 25, 2026, in Cañon City, Colorado. Staged at the Royal Gorge Ranch & Resort, the race takes participants along the rim of the Royal Gorge, famously known as the "Grand Canyon of the Arkansas." Runners navigate technical, rocky trails roughly 900 feet above the Arkansas River, traversing a landscape defined by dramatic cliffs and historic railroad routes from the 1870s. The event offers a comprehensive range of distances, from a 50K ultramarathon to a 5K and a dedicated Kids Run, providing a rugged mountain experience for athletes of all skill levels.

Cañon City is the county seat of Fremont County, Colorado, with a population of approximately 17,200 residents. The demographic profile of the city is 76.5% White (non-Hispanic), 14.8% Hispanic or Latino, 3.4% Black or African American, 2.3% Indigenous (predominantly Ute heritage), and 0.8% Asian. The median annual household income is approximately $53,000. Geographically, the area is situated at the edge of the Rocky Mountains, where the Arkansas River has carved deep granite canyons. In late April, the regional weather is notoriously unpredictable due to the high-desert and mountain interface; while average highs are around 18°C (65°F) and lows are 2°C (36°F), spring snowstorms are a documented possibility. Runners must be prepared for technical trail maneuvers along steep drop-offs and may be required to carry safety gear depending on the forecast.
The race is organized by Aravaipa Running and features amenities such as gender-specific shirts, chip-timed results, and custom finisher medals. While pacers are not permitted for any distance, 50K runners may utilize drop bags at the central start/finish area. Bib pickup is available on Friday evening at the Whitewater Bar & Grill or on race morning at the resort. Medical support is provided by on-site EMTs to manage the risks associated with technical mountain running and altitude. Registration typically closes on April 20, 2026, though the event encourages early sign-ups due to the limited parking and logistical constraints of the Royal Gorge rim. Proceeds and volunteer credits from the event support the continued development and maintenance of the regional trail network.
