With gyms across the country closing indefinitely these days, one of the best ways to stay in shape is by running. This cheap Garmin watch deal on Amazon can help you, whether you are a beginner or a seasoned runner.

For a limited time, Amazon is offering the Garmin Forerunner 35 for $89.99. That's $80 off and the lowest price we could find for a Garmin watch of this model. It's an older watch, to be sure, but it's inexpensive and has everything you need. (This price applies to the "black" model only.)

The Forerunner 35 has built-in GPS and a heart rate monitor; our review of the Garmin Forerunner 35 found it to be an excellent GPS watch with basic features.

The watch doubles as an all-day activity tracker and has smartphone notifications. The design is a bit plain, but the screen is easy to read in all conditions. I also like that it is waterproof to 130 feet (though it can only track walking, biking, and indoor/outdoor running). It also has Move alerts, which buzzes if you stop for an extended period of time.

As for performance, the watch did a solid job tracking our running with great accuracy. It is rated to last up to 9 days in watch mode and up to 13 hours in training mode.
