Abbie Chaffin
Running Coach
Abbie is a people-first running coach and fitness instructor dedicated to helping athletes unlock their potential and build lifelong running habits. A former soccer player and track runner, she discovered endurance running in 2013 after moving to Chicago, where the city’s vibrant running scene became a central part of her life. Since then, running has brought her strong friendships, global race experiences, and a deeper connection to movement as a tool for resilience.
Balancing multiple jobs while training for marathons and ultra-endurance events, Abbie understands that flexibility and consistency are key to long-term success. After leaving her corporate career, she transitioned full-time into health and wellness, now working as a Senior Instructor at Studio Three and a coach for Inner Lane. She has completed three World Marathon Majors (Chicago, Berlin, London) and plans to add more to her list.
Abbie is passionate about helping runners of all levels find their place in the Chicago running community, whether training for one race or a lifetime of running.
