Grand Mesa Ultra 50M

The Grand Mesa is a large mesa in western Colorado in the United States. It is the largest flat-topped mountain in the entire world. It has an area of about 500 square miles (1,300 km2) and stretches for about 40 miles (64 km) east of Grand Junction between the Colorado River and the Gunnison River, its tributary to the south. The north side of the mesa is drained largely by Plateau Creek, a smaller tributary of the Colorado. The west side is drained largely by Kannah Creek, which is received to the west by the lower Gunnison River. The mesa rises about 6,000 feet (1,800 m) above the surrounding river valleys, including the Grand Valley to the west, reaching an elevation of about 11,000 feet (3,400 m), with a maximum elevation of 11,333 feet (3,454 m) at Crater Peak. Much of the mesa is within Grand Mesa National Forest. Over 300 lakes, including many reservoirs created and used for drinking and irrigation water, are scattered along the top of the formation. The Grand Mesa is flat in some areas, but quite rugged in others.

This is a good old fashioned Colorado mountain trail race run at high elevation. This race takes place on the Grand Mesa (near Grand Junction, CO), known as the largest flat-topped mountain in the world. The terrain varies from rocky ridges, smooth single track, grassy meadows and pine/aspen forests with views galore! The average elevation is 10,000'. The highest point for each race is the summit of Crag's Crest at 11,200' where you can view many of the 300 beautiful lakes that are located on the Grand Mesa.
