Garmin Forerunner 165
Entry-level running watch with a 1.2" AMOLED display, 19 h GPS battery and just 39 g. Training metrics, adaptive plans and accurate multi-GNSS GPS for training and racing marathons. Garmin's gateway watch for runners who don't need maps or multi-band.
Why this watch
Peña Prieta SkyRace is an ultra: you'll finish in around 10h 42min. Your watch must record at least 14 h of GPS without recharging. Prioritise battery life and, if needed, drop to standard GPS mode to reach the finish with charge to spare.
