You're a runner, so train like one. The smaller-sized Forerunner45S is a fuss-free running watch that monitors heart rate at the wrist and uses GPS to track your pace, distance and more.
It works with free Garmin Coach adaptive training plans that bring personal coaching to your wrist. Stay connected when you want to with notifications for texts and calls.
Is this a good watch? With this lockdown I need a running watch to motivate me so I can get back into shape
