The Red Rock Canyon Ultra returns to Blue Diamond, Nevada on November 14th, challenging endurance runners with a variety of distances through the rugged landscape near Las Vegas, NV. This event offers three distinct race options: a grueling 100K course, a mid-length 50K option, and a more accessible but still demanding 17K route. The Red Rock Canyon Ultra begins at dawn on November 14th in Blue Diamond, with runners setting off from the visitor center of Red Rock National Conservation Area. The trail conditions are firm and slightly soft underfoot, providing both traction and some cushioning for long-distance efforts. Participants can expect a UV index of low 2.0 during race hours, suggesting adequate sun protection is necessary. Red Rock Canyon Ultra has been an annual event since its inception, attracting hundreds of runners each year to traverse the scenic yet challenging terrain around Las Vegas. The race supports local conservation and education initiatives in the area by raising awareness for environmental preservation efforts through participation fees. Runners are drawn to the unique geology of Red Rock NCA, with ancient Aztec sandstone canyons and limestone formations millions of years old adding a historical dimension to every step taken. The course itself meanders through diverse landscapes including quarries, washes, and canyons within the boundaries of Red Rock Conservation Area. Aid stations are strategically placed along key points in the route such as Lost Creek (7 miles), South Oak Creek (15.5 miles), Blue Diamond (19.5 miles), Mud Spring (25.75 miles for 50k, 33.5 and 37.75 miles for 100k), Red Valley (47.75 miles), Satan's Escalator (53.5 miles), and the finish line at mile 62.5. Runners must adhere to specific cutoff times which are strictly enforced, ensuring safety throughout the event. On race morning, participants can expect temperatures ranging from mild to cool with a firm trail surface for running shoes to grip securely. The UV index suggests light sun exposure is possible but not intense enough to necessitate extreme precautions beyond standard hydration and clothing needs. Humidity levels will likely remain low due to typical November conditions in the region. The Red Rock Canyon Ultra offers three distances: 100K, 50K, and 17K.
