Why we like it
- AMOLED screen stays readable in sun with optional always-on.
- Multi-band GNSS locked on routes faster than the Forerunner 255 in our city tests.
- Training Readiness combines HRV, sleep, and load into a clear morning score.
What to know
- No onboard maps—breadcrumb navigation only.
- Music storage adds ~1.5x battery drain with GPS + headphones.
- Two case sizes: 42mm (S) and 46mm share the same software.
Best for
- Runners who want bright visuals without sacrificing GPS precision.
- Interval training and race pacing with wrist-based power.
- Tracking recovery trends via HRV status and training readiness.
Performance in testing
We ran three structured workouts per week and tracked accuracy across environments.
GPS & pacing
Multi-band GNSS produced smoother tracks on city blocks than the Forerunner 255, with an average 1-2 meter deviation compared to a measured 5K route. Pace alerts are snappier, especially when using auto-lap at 1 km.
Training load & readiness
Daily readiness scores closely matched our perceived effort, downgrading the score after back-to-back VO2max sessions. HRV status needs two weeks of baseline but then updates reliably each morning.
Battery & charging
In mixed use with three GPS runs, notifications, and always-on at medium brightness, we averaged 6-7 days. Turning off always-on boosted endurance to 11-12 days. A full charge takes about 75 minutes with the included cable.
Health & sensors
Heart-rate accuracy stayed within 2-3 bpm of a Polar H10 chest strap during steady runs, though quick surges sometimes lagged by ~5 seconds. SpO2 readings align with a fingertip monitor but use more battery when left on overnight.

Pros & cons
Pros
- Bright, sharp AMOLED display without major hit to battery.

Verdict
A race-ready running watch that finally pairs Garmin's deep metrics with an eye-catching screen.
If you race, train for PRs, or simply want a reliable GPS companion, the Forerunner 265 hits the sweet spot between the lightweight 255 and the pricier 965. The AMOLED screen is the headline change, but the real win is how Garmin blends training readiness, HRV status, and daily suggested workouts into a cohesive coach-like experience.
