T.R. Maloney – Boulder CO

TR came to ultra running via bike racing and triathlons.  He spent 20-years in the cycling industry managing bike shops and then as a Product Manager for a bike company.  While training for Ironman Louisville he realized the longer events better matched his endurance engine.

After a couple years of 13.1’s and 26.2’s it was time for him to move up to the 50-milers. During a five-month span in 2011 he competed in the Run Rabbit Run 50, Pony Express 50 and Rocky Raccoon 50. An ultra runner was born…

TR lives and trains in Boulder, Colorado and can often be found running around Marshall Mesa and the surrounding trails with his wife Lisa.  In his spare time he wrenches on bikes for local pros, listens to 80’s hair metal and searches for the perfect 4-legged running companion.


Mirna Valerio – Georgia

Mirna is a born and bred New Yorker who currently resides in the North Georgia mountains (and yes, there are mountains in Georgia!) with her very handsome husband and increasingly sarcastic 5th grade boy. A classically trained musician, she teaches Spanish and choral music at a boarding school along with coaching both cross country and track.

She began her lifelong (but on and off) obsession with running in high school where she had to run a mile for the first time ever in her life. That was the beginning of the end. She now does marathons, has completed an ultra and looks forward to many, many more. Her dream even is the 6 day Trans Rockies Run. “I need to show us fat girls that we can be out here too, living, breathing, and beating the hell out of fat-people stereotypes.”

You can follow her adventures in both road and trail running on her blog at http://fatgirlrunning-fatrunner.blogspot.com/

Lara Robinson – Boulder CO – aka SMZRunner

Lara started running after a 20-year hiatus when it became apparent that her fat dog needed to lose about 20 pounds or die of a heart attack.  She quickly upped her mileage and within a year was running 10k’s and then her first Half Marathon.  Every Saturday morning she joined a group of women from her kids’ preschool and hit the trails.  Running in the hills of Boulder captured her heart and she began to blog about her weekly runs.  Within a few years her mileage had increased even more and in 2010 she ran her first marathon, followed 10 months later by her first Ultra.  Now, she’s double-dipping and training simultaneously for Ultra trail races as well as Marathons, having figured out that both are possible as long as the trail running is there to heal muscles brutalized by road and speed work.

Lara is a single mom raising her two kids in the Boulder area.  She writes a blog called Saturday Morning Zen that originally started as a way to record her thoughts about trail running but that morphed into essays about running, trails, training, and the intersection of thoughts and life that happen when we least expect it.  She’s the co-author of “Full Circle”, a book that’s still in production, and works as an Executive and Entrepreneurial Coach as well as a Project Manager.

Emily Berriochoa – Boise, ID

Emily Berriochoa has lived in the Boise, Idaho area since she was a kid. From high school to 2007, her relationship with running was frequently on the rocks. But when her baby girl was six months old, she got off the couch and started running again—for the last time. After shedding the baby weight, she ran her first marathon in 2008. But it was running the Big Horn trail 50k in 2009 that changed her life forever.

Emily feels that trail ultra running is the bomb, and as part of Team Pearl iZUMi Mountain States, she has the opportunity to connect with lots of runners and share the love. Emily’s favorite races are 100 milers, and she is working to unravel the mysteries involved in the distance. Emily runs really slow but doesn’t lose sleep over it. For her, time spent on her local trails—Ridge to Rivers and Wilson Creek—is where it’s at.

Emily and running partner Davina Jackson founded Pickled Feet Ultra Running in 2011 and currently direct three races for the company. When not race directing or running, Emily is a freelance designer and advocate for getting her kids (ages 6 and 10) out running.



Elizabeth Kimble- Arkansas

A native Arkansas, Elizabeth returned to the running scene after 8 years thanks in part to a local running clinic.  She began running in Vibram FiveFingers at the same time and hasn’t put them down since.  After finding 5Ks weren’t her speed, she happened to learn of a trail fun run…and the rest is history.  Now most of her races are on the trail, and recently completed her first 50K.

When she’s not running, you can find her slinging joe at the best local coffee shop in town, advocating for a cleaner, greener environment, or cuddling the other two members of her family – the cat and the husband, in that order!

Craig Lloyd – Draper UT

Craig Lloyd started running in January, 2009.  His meager beginnings have grown to become a local ultra-running character.  His love for adventure and silliness out-weighs his desire to race, although he finds time a few times a year to toe the line with the other crazies willing to sacrifice their time, body, and mind to the trail gods.  Thanks to his background in rock climbing and peak-bagging, Craig tends to target routes that are only a ‘little scary’, but most often lead to the tops of mountains.  He is the current Fastest Known Time holder of the Utah Triple Crown – Utah’s three tallest peaks, first person to run the Zion Double Crossing, and winner of the 2011 Laramie 100.  However, these feats pale in comparison to such achievements as – jumping over people downclimbing the crags at the 2009 Wahsatch Steeplechase, doing a backflip off of Mom’s Rock at Joe’s Valley, and eating an entire box of Otter Pops in a single sitting.

Craig works for a national telecom company, but is starting to grow his own public speaking and personal development company called A Life Worth Running.  When he’s not running or working he can be found playing with his four children or walking his slack-line in his backyard in Draper, UT.  His wife thinks he is absolutely crazy but still manages to find a little love in her heart for him. You can read about his personal exploits on his blog – refuse2quit.com.

Matt Williams – Salt Lake City, Utah

Matt spent his childhood exploring in the Wasatch Mountains in Utah, with many more years spent on trails from the back of a horse. Only in the last few years did he realize the vast opportunities that actually running on the trails would afford. Matt enjoys adventure running as a way to see spectacular scenery, with an occasional race thrown in. Living in SLC, Utah gives easy access to some of the best trails in the country. He has the support of an amazing wife and two sons, who really give him something to run for, and not from!

Matt is also part of the Refuse to Quit crew, whose exploits can be followed on Refuse2quit.com.

Pete Stoughton – Park City, UT

Pete grew up on the east coast and migrated his family out to Utah for the mountains. He combines his passions for the mountains with daily life as a teacher, husband and father. Pete has coached XC, lead wilderness and backcountry trips for adults and kids, taught Avalanche courses to students and lead group runs for years.

Still relatively new, in comparison to many of the greats, Pete has completed the Wasatch 100, and numerous other ultra distances. His favorite distance is the 50k, but as age starts creeping closer he finds those top end speeds hard to maintain.

Rebecca Schaefer – Philadelphia, Pennsylvania

Running since the 3rd grade, Rebecca has been hooked on running from a young age. When running in high school, the idea of running longer than a 5k was absurd, but the fun and pain of long distances eventually lured her in. First, it was just marathons, but that wasn’t enough. Since then, she’s run a handful of marathons, 12 hour races, 24 hour races, a 50k, and a 100 miler, mostly through faking it ’till she makes it and learning from the amazing ultra community.
