You do the running. Forerunner 245 does the thinking. This GPS running smartwatch evaluates performance stats such as VO2 max, aerobic and anaerobic training effect, and training status, which indicates if you're undertraining or overdoing it. You can also track advanced running dynamics such as ground contact time balance and stride length. Take the guesswork out of training for your next 5K,10K or Half-Marathon 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.
