Utah's original Backyard Ultra! The Bonneville Backyard Ultramarathon is a last man standing race. You must complete one 4.167 mile loop every hour to remain in the race. Our course is an out and back, so about 2.08 miles each way. The race will start at 9:00AM on April 26th 2025. About 5 minutes before that ALL runners need to be at the starting line so we can paint a corral around you. This will be the measure we use to see who will be continuing each loop. Three minutes before the start and every subsequent loop we will blow a whistle three times. At two minutes we will blow it two times, and one whistle at one minute until the race/start of the loop. Then at 8:00 exactly, and right on the hour for every other loop we will ring the bell. If you are not in the starting corral when the bell is rung you are out. NO EXCEPTIONS. Congrats on your DNF! Its nothing to be ashamed of, everyone except one of you will get one. For most people this race is not about winning, it is about finding your limit. Hopefully pushing it further than you thought possible. For more specific information please visit our website www.bonnevillebackyardultra.com and if you have questions please reach out!
Event's current local time: 1:52 AM MT
