Garmin Forerunner 965 vs 265: Which GPS Watch Should Marathoners Buy in 2025?

Garmin's mid-range and flagship running watches go head-to-head. Both offer AMOLED displays and advanced training metrics, but the price gap is significant. Here's how to decide.

Choosing between the Garmin Forerunner 265 and 965 is one of the most common questions in the running community right now — and for good reason. Both watches share DNA, both have beautiful AMOLED screens, and both offer Garmin's industry-leading training load and recovery metrics.

Where the 965 wins:

Titanium bezel (lighter, more premium feel)

Larger 51mm case with bigger battery (31 hours GPS vs 24 hours)

Triathlon and multi-sport modes

More detailed mapping with downloadable topographic maps

Morning Report with daily suggested workouts

Where the 265 punches above its weight:

Same Training Readiness, HRV Status, and race predictor

Same AMOLED screen quality (slightly smaller at 46mm)

15% lighter

£150 cheaper

Our verdict for marathon runners: If your primary sport is road running and you race 2–4 marathons a year, the Forerunner 265 covers everything you need. The 965 makes more sense if you also do triathlons or want the extra battery for ultras and long training runs.
