Sun Marathon
Race Day Weather
Cool start, gradual warm-up
Runners will face a cool start at 35°F, gradually warming to a comfortable 51°F. Winds will be a light headwind at 7 mph with gusts up to 27 mph, adding a challenge. With humidity at 54% and a low dew point, hydration should be managed effectively, but pace can remain steady throughout.
The Sun Marathon has four distances. Full Marathon, Half Marathon, 10K and 5K. This race purpose is to get runners out of the cold and into the warmth of Southern Utah in the St. George/Santa Clara Area. Though the courses are primarily downhill over the distance there are some rollers and a few climbs. The views during this race are great with huge red rock mountains all around to views of Gunlock Reservoir during the Marathon and a nice river along the Full and Half Marathons. Source
