Analysis: where they really differ
Two opposite takes on the trail watch. The Enduro 3 is Garmin's battery-life flagship: a solar-charging MIP display, 120 h of GPS, topo maps with routing and multi-band GPS, built for ultras and stage races where you never want to see a charger. The Forerunner 265 is a much lighter running watch (47 g) with an AMOLED screen, music and multi-band GPS, but only 20 h of GPS and no onboard maps. For races up to 50 km the 265 gives you nearly everything with less weight on the wrist; for 100 km or more, or if you navigate with maps, the Enduro 3 plays in another league.
Choose the Garmin Enduro 3 if…
- You run 100 km+ ultras and need 120 h of GPS without charging
- You want topo maps with routing and solar charging
- You prefer the sunlight legibility of an MIP display
Choose the Garmin Forerunner 265 if…
- Your races stay under 50 km and you want a light watch (47 g)
- You want an AMOLED screen and music on your wrist
- You want the best features-for-money balance in Garmin's range
