Steph Lefferts

Biography

Steph Lefferts is an avid trail runner, ultramarathoner, and the Tour Manager for Run the Alps. Though inspired by her father's extensive history in ultra-running, her own passion for the sport ignited during her senior year of college. Since then, she has completed numerous grueling ultramarathons—including the Leadville Trail 100 Miler and the Umstead 100—continually pushing her physical and mental limits. Her deep love for mountain movement led her and her husband, Mike Ambrose, to spend three years living and running in Annecy, France, an adventure that fueled her role in designing inclusive alpine running experiences and co-producing trail running films.
