50 Miler
Start to Aid 1 - 11.2 miles +3,714/-1,340 ft
This first section is the longest and most gnarly. All the more reason to get it done first on fresh legs and in the cool morning. You will go from smooth single track to a steep and rocky ridge. After following this ridge and descending back into the canyon will be one of the most scenic sections of the course. After this you hit another ridge followed by some dirt road running. You will then descend down some steep and rocky fire road to where you meet up with single track that will take you all the way to Aid Station 1.
Aid 1 to Aid 2 - 7.1 miles +2,107/-2,107 ft
This section is the wild child. You will climb up a steep and beautiful trail to the top of Butterfield Peak where you will be rewarded with an amazing view of the area. From here you follow the ridge and down some incredibly beautiful single track trails winding through the canyon. You will have a couple stream crossings that can be done while keeping your feet dry but we can't guarantee it. You will have to use the rocks and logs if you want to keep your feet dry. Once you leave the canyon you will follow a smooth single track trail back to Aid Station 2.
Aid 2 to Aid 3 - 5.0 miles +1,191/-1,191 ft*Cutoff for leaving aid 3 is 1:00 pm*
This section may appear dull due to being 100% dirt road but you will be rewarded with great views on your way up to the turn around. At the turn around you will be reward to the best view of all. You will be able to peer into the largest man made mine in the world. It is a beautiful view and also saddening at the same time when you realize a mountain once stood in its place. Take a few minutes for this view, it is worth it.
Aid 3 to Aid 4 - 8.8 miles +889/-2,959 ft
**Drop bag, pacer, and crew allowed - Parking at Yellow Fork Trailhead**
This section is nice and mellow minus one little patch of rocky steep dirt road. After the steep rocky climb you have miles of downhill dirt road running. After this you will be rewarded with a beautiful section of single track that will take you to Aid 4. Welcome to the Yellow Fork party!
Aid 4 to Aid 5 - 5.9 miles +1,206/-1,206 ft
*Cutoff for leaving aid 5 is 5:30 pm*
**Drop bag, pacer, and crew allowed - Parking at Yellow Fork Trailhead**
Hands down the most scenic section of the course overall. You will be amazed at the varying views you encounter during this loop. There is one big climb that offers great scenery the entire climb up.
Aid 5 to Aid 6 - 4.8 miles +837/-837 ft
*Cutoff for leaving aid 6 is 7:30 pm*
**Drop bag, pacer, and crew allowed - Parking at Yellow Fork Trailhead**
You start your way up a dirt road with unmatched scenery for a road. You will climb up one last time to the ridges only to drop back down on the incredible single track trails. Enjoy them while you can because you will leave for the finish line after upon reaching the aid station again.
Aid 6 to Finish - 7.8 miles +812/-1,065 ft
This section has it all as well. Great scenery, vistas, and single track trail. Do not underestimate this section due to the lower amount of elevation gain. By now it will be hot out and you will be exposed for much of this section. Bring plenty of water from the aid station. You will finish the last couple of miles on the beautiful and shaded Butterfield Canyon trails giving you that extra push to finish this race strong and hopefully smiling.

Navigation
Course is marked with pink flags, ribbons, signs, and trail marshals. The flagging will come before, during, and after the turn. This flagging will be on the same side of the trail as the turn. For example, a right turn will have flagging on the right side of the trail before and after the right turn.
We will only mark turns, trail changes or areas we feel need it. If you come to an intersection or see a trail branching off the main trail and there are no flags stay on the same trail and continue straight. This course will be well marked
*We will have trail marshals, signs, and cones directing runners at the Yellow Forks Aid station due to this being two aid stations. Makes it easy for your friends and family to cheer you on!
About Us
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 a 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 Mountains have 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: 11:25 PM MT
