About this product

Get ready for your next race with Garmin Forerunner 45 Plus. This GPS running watch doesn't just monitor heart rate and track your pace. It also includes training tools to help you monitor recovery between runs and predict your finish time. Even get on-the-wrist coaching towards your race goals with free Garmin Coach training plans that adapt to you. While you run, stay connected with text and call notifications, and feel secure with safety and tracking features that let you send your real-time location to emergency contacts.

Switch up your routine with built-in activity profiles for running, cycling, indoor track, treadmill, elliptical, cardio, yoga and more. Easy-to-use running watch monitors heart rate at the wrist and features GPS to track how far, how fast and where you've run.

Forerunner 45 Plus works with free Garmin Coach adaptive training plans that bring expert, personalised coaching right to your wrist. Make sure you're incorporating enough rest between runs with a built-in recovery advisor.

See how factors such as your fitness level and training history affect your predicted race time. Connected features include smart notifications for incoming texts and calls, automatic uploads to the Garmin Connect app, live tracking and controls for the music playing on your phone.

Safety and tracking features include incident detection (during select activities) and assistance, both of which send your real-time location to emergency contacts. Battery life: up to 7 days in smartwatch mode or 13 hours in GPS mode.
