Priced at $450, the Coros Pace 4 Pro positions itself as a “well-balanced” watch capable of appealing to both road runners and trail and ultrarunners. The brand highlights battery life of up to 60 hours in GPS, a fast-response touchscreen protected by sapphire glass, quick functions for managing routes and maps, as well as frequent firmware updates that add features after purchase.
Alongside being billed as lightweight, the Pace 4 Pro stands out for its screen size: 43 grams with a nylon strap, thickness unchanged compared with the Pace 4, and a screen said to be 22.5% larger. The watch also tops the Coros Pace 4 by “nearly 50%” more battery life. The article stresses that these choices (display, weight, price) make it a watch ultrarunners should consider.
In terms of display, the Pace 4 Pro adopts an AMOLED screen described as the brightest on Coros, with a quoted maximum brightness of 3,500 nits. The author reports using it for around 120 miles across varied conditions, including “bright sunshine” in Colorado as well as dark and cloudy days of a monsoon-like type. He says he encountered no readability issues, from maximum brightness to the most overcast conditions.
Navigation and map processing are described as fast thanks to a touchscreen and improved performance. The text mentions maps that are not preloaded, but instead are downloaded and synchronised quickly via the Coros app: around 30 seconds to download and synchronise the whole of Colorado, whereas the author says Suunto watches can take more than 30 minutes. Once on the watch, scrolling and zooming should be without any perceptible lag.
Lastly, the battery section details several modes with stated durations. In High GPS (single-frequency GPS), battery life reaches 60 hours; in High GPS with “always-on” display, 46 hours; in Max GPS (dual-frequency), 40 hours; and in Daily Use, 30 hours. The text also mentions an Auto GPS mode that can switch between single- and dual-frequency depending on the context, with the goal of balancing signal fidelity and power consumption.
