On Saturday, the Utah Valley Marathon was scheduled to begin at 5 am. The marathon according to organizers was "designed to take you along trails with the best views in the area."

 According to KUTV, 12 to 18 inches of snow had accumulated, resulting in near white-out conditions for the racers. Snowmobiles and 4X4 were used by search and rescue crews to aid the 87 runners. 

All the runners have subsequently been found. A number were treated for hypothermia with some only minimally clothed for the run.

The Davis Country Sheriff's Office officials posted a reminder on Facebook for those headed outdoors to familiarize themselves with the weather conditions, detailing that outdoor ventures with sudden weather changes can become life-threatening.
