Join Rocky Mountain Half Marathon 2025
Get ready to elevate your running experience at the Rocky Mountain Half Marathon and 5K in Estes Park, Colorado. This high-altitude race offers athletes breathtaking mountain views as you race just outside the iconic Rocky Mountain National Park. The paved loop half marathon course challenges runners with a 780 ft (238 m) elevation gain, reaching a peak height of 7,906 ft (2,410 m). Expect a combination of steady climbs and rolling descents culminating in a scenic finish around Lake Estes. For those seeking an extra test of endurance, tackle the Elk Double by completing both the 5K and Half Marathon. Beyond the race, enjoy the vibrant atmosphere at Stanley Park, featuring an expo and the warm hospitality of a mountain-town community. The demanding elevation offers both a test of fitness and a reward of stunning scenery every mile.
