A senior health editor tested four fitness watches for Hyrox training, a hybrid sport blending running with strength exercises. The goal: accurate heart rate, run distance, and easy exercise switching.

Winner for Runners: Coros Pace 4 The Coros Pace 4 automatically detects run segments, tallies total run mileage, and labels exercises as "functional training" for later editing. Its Hybrid Fitness mode includes options for training, racing, and fitness tests.
