The Wasatch Back is part of the relay series known as Ragnar. The more than 11,000 contestants travel throughout the night and will take turns running the almost 200 miles through the northern Utah mountain range.
Teams of 4 to 12 people flock from all over the country to participate in what has become the biggest relay race of its kind.
Participants say the poor weather conditions wasn’t enough to stop them from competing.
“I hope it does not rain because I only brought one pair of shoes," said one team captain.
Spokesperson Elise Timothy said this makes such an amazing event as they have help from more than 300 local volunteers.
“We could not do this without our great volunteers,”Timothy said.
The race will end by 6:00 p.m. on Saturday at Park City High School.
