Who, What, Where, and Why

Butterfield Trailhead Regional Park sits in the shadow of Kennecott Mine and the Oquirrh Mountains. This park is new and designed to give access to the new Butterfield Trail system as well as host events both big and small. We will be setup in the event parking which will provide plenty of room for Backyard runners to get comfortable and settle in for the long and fun day. We hope you come out to push yourself and have a good time with friends and family at the finish line.

Backyard races have exploded in popularity around the world. The race is simple and yet imbues everything a runner looks for in a race. We have taken the best parts of the backyard and added our own little twist with the Legacy loop at the end of each backyard event. Comradery, motivation, great outdoors, and food, lots of food.

This race is a 4.167 mile loop course that runners will do once every hour for either 12 hours total or 24 hours total
If you are unable to complete a loop in the hour or choose to not start a loop at the hour, you are removed from the race
All runners who complete at least 1 loop will receive a finishers medal
All runners who complete 50 miles and 100 miles will receive a custom leather patch beanie
The goal is to push yourself to new limits. You will never know how far you can run until you try
Finish line becomes home base. Fun for friends and family to come cheer you on and hang out
Backyards require a sound strategy with how you manage your hour as well as being physically and mentally tough
Legacy loop will be the 12th and 24th loop and will be timed to determine the overall winners

Seriously though, when we first heard of this new race idea we thought it was crazy. The more we thought on it the more we realized just how amazing and fun this kind of setup is.

Runners of all levels can participate, great way to push yourself to new limits, and the finish line turns into the best aid station you ever had. What better way to spend your Saturday than hanging out with fellow runners in the great outdoors.

We chose a 12hr and 24hr format to make this more runner friendly and help with planning and logistics for both us as organizers but also the runners.

Give the Backyard Ultra a try, you might just enjoy it. Makes for a great story!

About

At Happy Trails Running we focus on a beautiful course and an amazing experience. We want our races to be events that runners look forward to every year. We believe in quality over quantity which is why we cap all races at 300 or less participants. This lets us hold races in unique areas that would be off limits to large race due to parking and trail capacity.

We also believe in keeping everything local. This enables us to both support our community but also keep costs down. We want our races to be simple, affordable, and convenient for runners. You won't find huge expos at our races, just local businesses, friends, and family having a great time!

If there is anything we can do to improve your experience with our races please reach out to us. We are always trying to improve our events. Your feedback, what you liked and did not like, is the best way to achieve this.

Our courses will not focus on setting PR's with mostly downhill running but instead on enjoying all of the beautiful trails the Wasatch Front area has to offer. We hope our races will make lasting memories and experiences for all of our runners.

If it doesn't challenge you, it won't change you!

We hope to see you at the races or on the trails. Until then, Happy Trails! 

Event's current local time: 6:13 PM MT
