Garmin Forerunner 745 GPS Running Watch - Advanced Training Metrics

In this review of the Garmin Forerunner 745 the bottom line is simple: this is a focused multisport GPS watch for serious runners and triathletes who want deep training data in a compact package. The Forerunner 745 stands out for its on-device workout suggestions, compatibility with structured training platforms, and detailed running, cycling and swimming dynamics that help athletes plan and adjust training without carrying a phone. If you value advanced metrics, music storage and contactless payments in a lightweight wearable, this review finds the 745 delivers those essentials.

Key Features

• Multisport tracking: Preloaded activity profiles for running, triathlon, cycling, pool swimming and track running let users switch modes quickly during workouts and races.
• Accurate GPS: Uses multiple satellite systems to accurately track routes and distance for outdoor runs and rides without frequent corrections.
• Daily workout suggestions: On-device run and cycling workouts adapt to your current training load and VO2 max to help structure recovery and intensity.
• Third-party workout sync: Sync structured indoor or outdoor workouts from platforms like TrainingPeaks or TrainerRoad when paired with a compatible smartphone for guided sessions.
• Music on the wrist: Store and play up to 500 songs and connect with streaming services via smartphone to leave your phone behind on runs.
• Everyday convenience: Garmin Pay contactless payments and smartwatch functions simplify errands and daily life while training.

Who It's For

The Forerunner 745 is best for triathletes, competitive runners and dedicated cyclists who want advanced performance metrics without the bulk of larger sport watches. Its combination of swim, bike and run profiles, plus detailed dynamics, makes it especially useful for athletes training for races who rely on VO2 max and training load guidance.

Less suitable users include casual fitness trackers who only need basic step and heart rate monitoring or those who want extreme battery life for multi-day ultra events; while battery life is solid for daily use, the 6 hours in GPS with music and up to 30 hours in UltraTrac may not match larger long-endurance devices.
