Our Coaches

Erin McGrath

Head Coach - Full Marathon

Erin’s been running since 2007 and is running her tenth marathon this year – she’s lost count of her 5ks, 10ks, halfs and other weirdo distances. This is her ninth year running with USAFit Boston, and fifth year coaching. She loves running because she truly believes that anyone who wants to run, can, and is always thrilled to get her friends running with her. Erin’s training philosophy is that even a bad run is good for teaching you something, and that you can always work in a few more hills.


Scott Lennox

Head Coach - Full Marathon

Scott returned to running in 2002, 37 years after he last ran in college. He was convinced by a good friend and fellow John Hancock associate to run the 2003 Boston Marathon together through the company program. Completing the race was a life changing experience. Scott has now run 59 marathons including 15 Boston Marathons. He began coaching with BostonFit as an assistant 11 years ago and has been a head coach for the last 8 years. In 2009, his daughter, Beth, began running and they have completed many races together including 25 marathons to date, most memorably the 2014 Boston Marathon, as well as coaching together for the past 7 years. In recent years, both his niece Rebecca and daughter Mandy have taken up the sport, expanding his running family.  His greatest rewards from running and coaching have been the shared experiences with his family and the many friends he has made through the years.


Rebecca Chaplick

Head Coach - Half Marathon

Rebecca started running with BostonFit in 2014, and trained with the Purple team that season for her first half marathon. Since that time, she has fallen in love with the sport, and has run 25 half marathons and 2 full marathons. Her favorite part of running is the camaraderie and support she gets from her fellow runners, and the feeling of accomplishment that comes from crossing a finish line after putting in a season’s worth of hard work during training. She is excited for her third year as the half team head coach and helping others reach their running goals!


Shandi Foulger

Assistant Coach - Half Marathon

Shandi started running in 2011 when she moved to Boston, and quickly found herself craving longer and longer distances. She found USAFit Boston in 2013, and has trained for both half and full marathons with the group. So far, she has completed 6 marathons, and 14 half marathons. While she loves race day, she often finds training for a race to be more rewarding than the race itself, especially with a supportive and encouraging group like this one. This is her third year coaching, and she’s looking forward to helping more runners find joy in their runs and reach their goals.

Robin Dawson

Head Coach - ATP

Robin joined USAFit Boston in 2010 after moving to Boston and has run with the Advance Training Program (ATP) since then. Robin first started running in high school and has continued to make running a part of his life. Robin started coaching the ATP group in 2012 and has helped many runners improve their marathon times, many of whom have qualified for the Boston Marathon through the ATP program. The extra conditioning and preparation of the ATP group is perfect for people with running experience who want to improve their marathon performance.

Aime Macdonald

Organizer - Assistant Coach

Aime has been running since the days of racing other kids at the bus stop in elementary school, later running competitively in high school and college. Upon moving to Boston for grad school, and witnessing her first marathon in person, she did what most people do (right?), signed up for her hometown race, the New York Marathon! She has completed 10 marathons, countless races of other distances, racked up some weird race bling, overcome many an injury and met amazing friends along the way! She joined Boston Fit in 2007 and this is her fourth year coaching. She loves helping runners get over the limitations they put on themselves and enjoys post run meals. She has an unhealthy obsession with her favorite sports teams, enjoys singing during long runs, anything from Baby Shark (thanks Riley) to Bon Jovi, and is a proud runNerd!

Beth Lennox

Organizer - Assistant Coach

Beth has been running since 2009 when she “caught the bug” from Coach Dad. Since then, she has completed 29 marathons and many shorter races, and in addition to coaching for BostonFit she and her father have coached the Hale Reservation Boston Marathon team together for the past seven years.  Some of her favorite marathons so far include the Hartford Marathon (her first), Louisiana Marathon (Baton Rouge), and Rehoboth Beach Marathon (DE), though the most meaningful to her was the 2014 Boston Marathon.  Beth’s favorite thing about running is the fantastic people she has met through the sport, and she is looking forward to another great season with the BostonFit crew!
