Garmin Forerunner 45
What’s the story?
The slimline Forerunner 45 is the go-to watch for most runners. With an optical heart-rate sensor and up to seven days of battery life (13 hours with GPS on), it covers the basics in a comfortable no-frills package, while stats like VO2 Max and Body Battery help you to understand how healthy you are without requiring a degree in sports science.
