Kathleen Boucher-Lavigne is excited to join the Cto5 team! She joined Merrimack Striders in 2024 when she was training for her first marathon. A collegiate goalie in field hockey and lacrosse, Kathleen liked to sprint but loathed long distance running…until recently. She has loved realizing how much stronger she is than she gives herself credit for and will bring an upbeat personality and sense of humor to supporting you in your Cto5 goals! In addition to helping everyone find their pace with her affirming attitude, she leverages her background of a Master of Science in Exercise and Sport Studies as well as a master’s in teaching. She currently teaches middle school science at the Pike School. Beyond Cto5, Kathleen’s next running goal is training for a marathon in April with a fellow Strider!
