Details

Performance: This is a watch built for hardcore use! With a stainless steel case, the choice of metal or silicone band, and sapphire glass, you've got a watch that will survive any marathon or training regimen.

Despite the rugged design, it's a surprisingly sophisticated watch, built with a lot of features to help you track run performance. The built-in GPS sensors will help you track your location in the marathon, and the 3-axis compass will keep you from getting lost. With a gyroscope and barometric altimeter, you have everything you need to stay on course to the finish line.

The watch has a built-in widget that displays your training load, training status, and smart notifications. Thanks to its compatibility with Garmin Connect, you can upload your data to the online community and personalize your digital watch features.

Features: The watch comes with full-color TOPO U.S. maps, complete with the option to program your routes ahead of time. The GPS tracker is highly accurate and will help you stay updated on your position in the race.

The built-in heart rate monitor is fairly accurate, though its ANT+ compatible, so you can connect it to any chest strap monitor. The digital features include settings for not just running, but also cycling, cross-country skiing, climbing, HIIT training, and so much more. With the basic smart watch capabilities, you can check your texts and receive alerts of new messages or emails.

Price: At almost $700, this is a VERY pricey watch. However, for dedicated marathoners that need a watch that can keep up with their training, it's an investment worth making.
