Analysis: where they really differ
Two light running watches with an AMOLED display, multi-band GPS and music, but with different priorities. The Garmin Forerunner 265 has the most mature training-metrics ecosystem (load, recovery, plans) at 47 g, though it has no maps and reaches 20 h of GPS. The Suunto Run 2 weighs 53 g with strap, goes up to 24 h of GPS and includes free offline maps and a display of up to 2,000 nits. To train with data and plans, the 265; to head into the mountains with maps and a bit more battery, the Run 2.
