Utah > Only Half Crazy Half Marathon
Herriman, UT  •  Saturday, September 14, 2013  •  Course Map

Rising more than 10,000 feet above the valley floor at their highest point, Utah's Oquirrh Mountains stretch roughly 30 miles along the western edge of the Salt Lake Valley, making for an impressive scenic backdrop for runners at the newly renamed Only Half Crazy Half Marathon, which makes its third annual running on the weekend after Labor Day in September 2013.

(For its inaugural running in 2011, the race was named the South Valley Half Marathon, which saw just under 150 runners cross the finish line. At the race's 2012 running, exactly 150 runners crossed the finish line.)

Runners start and finish the point-to-point course for the race near the small town of Herriman in the part of the region known as Utah's South Valley, and can expect to encounter a course with long, gradual downhills as well as one long, gradual uphill stretch. At the starting line, the course elevation is estimated at 5,673 feet above sea level; at the finish line, the elevation is 4,626 feet.

The course starts about five miles southwest of Herriman in the area known as Yellow Fork Canyon, a popular park area for hiking and mountain biking from the late spring through the mid-fall season, as it's usually covered with snow during the winter months. From there, runners follow the route all downhill for the first four and a half miles or so along Rose Canyon Road, until they reach the western edge of Herriman.

At the intersection of Rose Canyon Road and Herriman Highway (West 13100 S), runners turn left and begin the race's one big uphill stretch, which unfolds over the next three miles as runners make their way along the Herriman Highway and Highway 111. Once runners pass the mile 8 marker, the course crests and then begins a second long, gradual downhill, this time all the way in to the finish line along Daybreak View Parkway, just north of Herriman.

Runners should be prepared for plenty of sun and warm temperatures, as the race takes place in early Sptember, when area temperatures can reach the 90s in the afternoon (though during the race, which starts at 7:00 AM, temperatures should be considerably cooler). The event is limited to 1,000 runners, and the time limit to complete the race is 4 hours.
