404: Charlie Sweeney, Pro Runner & Community Manager at Coros

This week on Marni on the Move, I'm joined by professional runner and COROS team member, Charlie Sweeney. Fresh off a 19th-place finish at the 2025 Boston Marathon—with a personal best time of 2:12:00—Charlie gives us a behind-the-scenes look at what it really takes to compete at the elite level while holding down a full-time job in the endurance sports tech world. We talk about how he got into running, what pushed him to go pro, who’s coaching him, and how he manages a training load of over 130 miles per week. We also dive into the gear he trusts, including the shoes he races in and how COROS plays a role in his training and recovery. Whether you’re training for your next race, dreaming of the pro path, or just love a good deep dive into endurance performance—this episode is full of insights and inspiration.
