About this event

What is the Endless Day Backyard Ultra? EVENT RESCHEDULED Due to the unhealthy air quality because of local forest fires, the Endless Day Backyard Ultra has been rescheduled from June 27 to October 17. Please join us for this new day that will be epic - and endless!How far can you go? Run one lap, or run all day, or even all night! Introducing the Endless Day Backyard Ultra.This isn’t your typical ultra. Every 90 minutes, you start a new 6.55-mile loop Keep going as long as you can… up to 24 hours Stop when you want—and STILL earn your distance Earn race milestones:• 1 lap = 10K (90 minutes)• 2 laps = Half Marathon (3 hours) • 4 laps = Marathon (6 hours)• 5 laps = 50K (7.5 hours)• 8 laps = 50 Miles (12 hours) • 15 laps = ~100 MilesYou must complete each lap within 90 minutes. If you do not like the pressure of a “last one standing” event, come challenge yourself on any distance you like and earn a distance milestone medal. But in the end, there will be only one winner - so whoever goe

s the furthest within the time limits is the winner. If several are still standing on the last lap, whoever finishes that lap first will be crowned the winner. Just you… the road… and one very long day.Registration: Priceless. But since there are expenses to cover, the registration will be based on the number of laps you intend to run, and ias follows:1: 1-6 laps (10K, half-marathon, Marathon - the fun runs) $65, regular registration; $85 after October 42: 7-15 laps (50K, 50 Miles, 100ish miles) $90, regular registration; $110, after October 4What Can You Expect in Return?As many miles as you chooseFlat dirt roads. Farm fields. Big skies.Your finisher milestone mementoAn epic Endless Day race hatNew friendsAmazing views of the Pahvant Range and Red HillsA course you’ll know by heart by the end Weather Prep & Base Camps The weather in October in Central Utah is quite unpredictable. Be prepared for sunny, windy, snowy, or a combination of all during the day. So keep an eye on the weather and

prepare your gear, hydration, and heating or cooling strategies appropriately. Any pavement? Just the 3 city blocks from the Nielson Family Park to the farm roads. Aid Stations: A full aid-station spread (aka The Oasis) will be at the start/finish park area, one another aid station about 1/2 way through. Given the potential for excessive heat, two other self-serve coolers will be out. Base Camp Is there room to set up a personal tent / base camp? Sure, the Nielson Family Park (band new the past two years) is an entire city block, so lots of room to set up your own personal base camp. We'll rope off areas around the start/finish around the Northern pavilion. Event's current local time: 2:52 AM MT
