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 10 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 and her sister, Becky, pacing in the 2023 Missoula Marathon.

Abby works as an early intervention special education teacher, which also involves a lot of running around. On the weekends you can find Abby eating, cuddling with her cat, or adventuring with her partner.




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 husband and two kids.

Running has always been a part of her life, from sprinting on the track to training for road races, but last year she decided to make the jump to the marathon. She completed her first in June at the Missoula Marathon, and her second in October at the Chicago Marathon. Both were incredible experiences and races, and neither would have been as successful without the RWM Marathon Training Class.

After a year of marathoning, she is excited to start off 2023 chasing down a new PR for the half marathon, and helping others reach their own running goals!

"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."
