The race kicks off at dawn, marked by a ringing bell and a series of whistle alerts. Participants will have one hour to complete a distance of 4.167 miles at the stunning SP Crater, featuring a mix of dirt trails and roads along with an elevation gain of about 150 feet. Runners will enjoy breathtaking views of the crater and Peaks as they race against the clock. Competitors must return to the starting corral each hour to continue, with the challenge intensifying until only one runner remains capable of completing the course. This unique format of the Backyard Ultra truly tests participants' limits, pushing them to discover their potential as they strive to outlast each other on this demanding course.
