Apple Watch Ultra 4 vs Garmin Forerunner 970 specs comparison
The Forerunner 970 is the stronger running and triathlon watch. It gives you Garmin’s training ecosystem, full mapping, much longer battery life and a lighter design, while still packing features such as ECG, multi-band GPS and an LED flashlight. The Ultra 4 is more rugged and much more capable as a smartwatch, with cellular connectivity, stronger apps and deeper integration with the iPhone. Pick the 970 primarily for training. Pick the Ultra 4 if sport is only one part of what you want from the watch.
