Pace 4 Nylon

What weighs less than a single gel packet and helps you train more effectively and race faster? There could be several correct answers to this question, but in this case, we think COROS' PACE 4 is the best choice. Not to mention that none of the other options track your sleep quality or heart rate. Neither do they offer real-time weather, free training plans, or the ability to record voice memos. In fact, we're baffled at how much technology has been squished into this tiny, lightweight wonder. The PACE 4 is the perfect companion for athletes who want to track their fitness without drawing attention to their watch. With its incredibly sleek design and lightweight build—lighter than your next snack—it's the ideal fitness tracker for everyday use. Redesigned heart rate sensor has better accuracy. Touch screen display for easy navigation. Real-time weather updates from up to 5 saved locations. Watch battery will outlast your fitness level. Back to start navigation function.
