A GPS with multiple sports modes to help you train harder and more efficiently than ever.
Multiple Sports Modes
Sync your watch with TomTom’s Sports App and unlock multiple sports modes: track your gym workouts, runs, cycles, swims and more. The App will help create over 50 personalised workouts that adapt to your improving fitness level as you achieve each of your personal, pre-set fitness goals. Comes with 5 pre-defined workouts built into the watch for when you are in a rush: fat burn, endurance, fitness, speed, and power. Also comes for real-time, motivational, coaching for all of your workouts.
GPS Tracking
Like all TomTom products, the Spark 3, promises premium GPS that will track your speed, pace, distance and location data during your sports.
24/7 Activity Tracker
Track your activity all day, every day. It’s not just workouts that are tracked: tracks your steps, heart rate, calories burned, and sleep 24/7. Even when you aren’t training set yourself daily step goals and track your progress via the app. Monitor your sleep to see if you are getting enough rest.
shame this doesnt store music (despite what the description says), that's going to set you back $210 but nets you HR
