For the ultimate athlete -- and especially triathlon trainees -- there's Tom Tom's Multi-Sport GPS watch. While most other fitness-tracking watches at CES only monitor users' progress running, cycling or swimming, Tom Tom's watch can track all three. It also includes built-in GPS technology for athletes to brave those new running or cycling trails worry-free.
A built-in graphical training partner lets users' track their training goals and progress at a glance, but the watch also syncs to Tom Tom's MySports website, where they can see dashboards, maps and other visuals depicting their distance, pace and other stats.
The watch sells for $199 on tomtom.com.
