Run Wild Missoula

Missoula Marathon & Half Marathon Training Class

March 3- June 30, 2024

The ORIGINAL Marathon (& Half) Training Group!


Since 2007, this class has been offered to Missoula area runners and walkers. This class is tailored specifically for the Missoula Marathon & Half Marathon. Run Wild Missoula has trained hundreds of runners of all abilities throughout the years to the iconic finish line on Beartracks Bridge! Never run a mile? Great! We got you. A seasoned runner or multiple Missoula Marathon finisher? We got you too! This is a great class to take whether you are a first-timer or repeat runner looking to successfully train for and complete either event during the Missoula Marathon weekend!

Runners and Walkers of all speeds, experience and abilities are welcome! Please note, the walking portions of the class are intended to support the completion of the Half Marathon. 

For 2024, we’ve added a Runner Education Series on Wednesday evenings for a more focused distribution of information and to get you out the door quicker on group runs.  

Come join us to run the Last Best Race in the Last Best Place!

Meet Your Coaching Team!


Class Coach & Leader: Abby Margolis

Abby grew up in Chappaqua, a small suburb outside of New York City. In 2016, she moved out to Missoula to be closer to her sister and never looked back! Abby ran her first half marathon in 2018 and first marathon in 2019–both in Missoula! Since then, she has completed 12 marathons. Her favorite running terrain is long, flat, open road, but she is occasionally convinced to run on hilly trails. Abby is a graduate of the Missoula Marathon Training Class and couldn’t be more excited to lead the class. And on race day you’ll find Abby chasing a personal best!

When Abby isn’t running, she’s talking about running, cuddling her cat, adventuring with her husband… or a combination of these. 




Assistant Coach: Tim Mosbacher  

Tim Mosbacher is an experienced marathoner, having run 63 marathons around the United States and abroad.   He is a former collegiate runner as well as a former high school cross country and track coach.   After completing two “disappointing” marathons, in 2009 Tim joined the RWM Missoula Marathon training class. Three marathons later, Tim led the RWM Boston Training Group for a number of years. Tim has completed a marathon in every state, with all of those completed in a Boston Marathon qualifying time.   He is a member of the 50 States Marathon Finisher Club, 50 States Sub 4 Hour Finisher Club, Boston 50 Running Club, and the Marathon Maniacs Club.



Assistant Coach: Braelynne Shell

Braelynne is a native Montanan who grew up in the mountains outside of Helena. Braelynne is a middle school teacher, and when she isn’t running, she loves to read, bake, and spend time on the trails with her kids.

Running has always been a part of her life, from sprinting on the track to training for road races to playing in the mountains on trail runs. She completed her first marathon in June 2022 at the Missoula Marathon after being a participant in the RWM Marathon Training class. She did her second marathon the following October at the Chicago Marathon. Both were incredible experiences and races, and neither would have been as successful without the RWM Marathon Training Class. Now, though, Braelynne is excited to continue focusing on races like the half marathon distance, and supporting athletes who also find joy in running.


Assistant Coach: Julia Crocker

Julia grew up in Norman, Oklahoma where she discovered running in an unusual way. The local cross-country coach would bring her dogs to all the meets and Julia was in charge of making sure they stayed off the course and out of the way. She fell in love with how muddy the runners got and how some races had hay bales the runners had to jump over. Her first race was a mile fun run in fifth grade and a high school runner ran it with her, but backwards. She has been running since! She has run collegiately in 5k track races to marathons her friends convinced her would be fun, but her passion for running comes from those hilly Oklahoma cross-country races, so you will find her more on the trails. Julia left the teaching profession in June where she also coached, so she is excited to be able to continue her passion for creating a positive training environment!

"I joined RWM only a year ago when a girlfriend encouraged me to join her in the Beginning Runner Class that RWM hosts. The running community has been a godsend for me and has helped me though a really tough time personally. Thanks to my friend that got me started and thanks to RWM. I love my running buddies --- all new friends and I love the change that has taken place in my life."
