You do the running. Forerunner 245 Music does the thinking. This GPS running smartwatch evaluates performance stats such as VO2 max, aerobic and anaerobic training effect and training status, which indicate if you’re undertraining or overdoing it. You can also track advanced running dynamics1 such as ground contact time balance and stride length. Sync your favorite music from select streaming services, and even store up to 500 songs right on your watch for phone-free listening. Take the guesswork out of training for your next 5K when you team this watch with the Garmin Coach app. Select free training plans that adapt to your goals or take training into your own hands by creating custom workouts at Garmin Connect, our free online fitness community.
