The Garmin Forerunner 45 is a basic running watch for beginners. But there’s nothing basic about it, considering it's packed with training workouts, health monitoring, safety features, and profiles for cycling as well. Its simple and lightweight design comes in two size options: the Forerunner 45 has a 42 mm diameter, while the 45S has an even sleeker 39 mm diameter. The sweat-ready silicone band fits comfortably and won’t chafe, and you'll love the sunlight-readable color display.
