Measure your overall energy efficiency while running — using long-term running volume, stride length and step speed loss, which tells you how much you slow down when your foot hits the ground — when you pair your watch with the HRM 600 heart rate monitor (sold separately).

Better understand the impact each run has on your body, and get a recommended weekly maximum mileage so you can keep training effectively without taking on too much.

Whether you’re running on city streets or riding densely covered trails, the Forerunner 970 smartwatch provides full-colour, built-in mapping — now even more dynamic, intuitive and simpler to follow.
