COROS has announced a partnership with middle-distance phenom Cooper Lutkenhaus.
After a historic 2025 season that saw him run 1:42.27 for 800m (lowering the high school record by over 5 seconds), Cooper turned professional in his junior year and has wasted no time making an impact. He opened his pro career with wins at both the Dr. Sander Scorcher (800m) and the Millrose Games (600m), establishing himself as one of the most exciting young talents in the sport.

Why Cooper?
At just 17 years old, Cooper already brings a thoughtful, intentional approach to his training and performance. "I love to look at the heart rate. If that's workouts or just easy runs. I've always been interested on, you know, if I feel really bad, is the heart rate going to be really high? Or if I feel really good, what's the difference?" he said. "And then during workouts, something that I try to do is see how low I can get it in between reps."
This data-curious mindset makes Cooper a natural fit for COROS. He and his coach often review post-workout data together. It's easy to forget now that he's a professional, but Cooper still faces the day-to-day life of a high schooler. "It's a little harder just because we can't have phones in school," he said. "But we kind of look at it the next day and just see."
Cooper recently ran a U20 Indoor American Record in the 800m in 1:45.23. He followed that with a win at the Millrose Games in the 600m with a U20 World Record of 1:14.15. Those performances provided an inside look at this fitness and training.
