Here at the High Lonesome we believe the best races are built by runners for runners. We feel extraordinarily lucky to have such an experienced team of people organizing this classic Colorado trail race. Together, our leadership committee has a collective 24 - 100 mile finishes (that's just finishes...we don't count the DNFs), 35 years of ultra-running experience and we’ve lost track of the number of races we've completed We don't say this to brag (ok, maybe just a little), but rather to assure you that we get it. We’ve got your back. They say it takes 10,000 hours to master a craft and we feel that together, with our cumulative experience, we’ve been able to create a truly amazing event. Don't take our word for it though, come out and see for yourself.

Caleb Efta - Race Director & Founder

Caleb Efta - Race Director & Founder

Caleb started running ultras 8 years ago when his brother-in-law dared him to run a 50k. Things snowballed from there, and after a move to Colorado in 2013, the High Lonesome 100 began to form. Caleb loves getting his friends to run, and finds true happiness in watching people dig deep and endure. He's a lover of details and notoriously picky, and channels both those into continuously improving the High Lonesome. When he's not running, you can find him eating hamburgers, drinking whiskey, and chasing snow.

For 2017, Caleb is running the Collegiate Peak 50 mile, Bighorn 100, Leadville 100, and the Rut 50k. But don't worry, his main goal is to make sure that you have your best race at the High Lonesome.


Jon Clinthorne - Course Director

Jon Clinthorne - Course Director

Our resident PHD holder, Jon brings a ton of ultra-running experience to our team. Over his 9 years of ultra-running, he has ten 100 mile finishes, many with podium or top 10 finishes. His skill set isn't limited to 100s though, he's won the Collegiate Peaks 50 miler and several other shorter ultras. When he's not running, you can often find Jon backcountry skiing, drinking a new beer, or relaxing with friends and his dogs.

For 2017, Jon is running the Bear 100, Black Hills 50, and potentially a few more.


Zach King - Logistics

Zach King - Logistics

Back when the High Lonesome was just an idea, Zach was the first person to jump on board and over the years his contributions have been invaluable to say the least. His vast array of talents has touched almost every aspect of our Colorado trail race, from website to aid stations and beyond. Trust us when we say that without Zach this race would not be what it is today. Yet another talented 100 miler, Zach has run Bear, Leadville, and Bighorn (a 4th place finish no less) under 24 hours. Only Wasatch has eluded him in the sub 24 mark, but he'll be back to better his 26 hour finish there. 


For 2017, Zach is running Pine to Palm 100 and the San Juan Solstice 50.

John Wros - Cartography

As an Alaska resident, John keeps us all jealous with his adventures up north. A professional cartographer and conservationist, he brings a unique skill set to our team. He's no running slouch either. In 2016 he finished in the top 50 of UTMB, and has four other 100 mile finishes to his name. 

For 2017 John is running the Sun Mountain 100k and Ultra Tour Monte Rose 170k.

For 2017, Leah is training for the Dirty Thirty 12 miler.

Julia German - Legal

Julia is also a new addition to our team, but has jumped right in by provided us with her prodigious legal talents. When she's not working, you can find her running the trails around Boulder.  Julia has three 100 milers to her name, including the challenging Fat Dog 120.

For 2017, Julia is training for her second finish at the Bighorn 100.


David Fox - PR

David Fox - PR

A recent convert to ultra-running (but a long time marathoner), David made good work of his first season by knocking out three 50ks. He is also the tireless coordinator of the Golden Mountain Runners, a local trail running group whose members make up a significant portion of our volunteers. Throughout the creation of the race, David has been a steadfast sounding board and giver of the best hugs. He's also a master proof reader, which has been no easy task since none of us can boast stats about the Spelling Bee’s we won.

For 2017, David is going to take a rest year and focus on being a power-pacer.

Kelsey is what many would call a pinch hitter, and she's a damn good one. She's always ready to help in any area and is a regular sounding board for many of the ideas and projects that come through our pipelines. She has a knack for editing copy, and has affectionately earned the nickname "the red wedding" due to her thoroughness with a red pen. Kelsey caught the ultra-running bug in 2016 with a finish at Dirty Thirty 50k.

In 2017 Kelsey is running the San Juan Solstice 50 miler, Never Summer 100k, and the Rut 50k.
