However, the Forerunner 965 is the more expensive variant, with a 1.4-inch AMOLED display and a battery life of up to 31 hours (in GPS mode) and up to 23 days (in smartwatch mode). In addition to retaining all of the capabilities of the cheaper model, it tracks additional performance indicators such as load ratio (the link between an athlete’s training load and what they can tolerate), real-time stamina data to manage exertion levels, and precise climbing measurements (including gradient, distance and elevation gains). The watch also has built-in navigation and greater music storage.
