Propelling GPS technology into the limelight of exercise training regimens worldwide, the TomTom Multi-Sport GPS Watch provides runners, bikers, and swimmers with accurate, real-time metrics to enhance performance, and it gives a baseline for future workouts. Engaging with your every stride, stroke, or pedal, QuickGPSFix Technology precisely pinpoints your location within mere seconds, tracking your every move in conjunction with a built-in, 3D accelerometer. The accelerometer allows this watch to be used indoors while you're running on a treadmill or swimming laps at the pool (doesn't work in open water). The super-comfy, perforated rubber watch strap won't stick to your wrist when the sweat starts to pour, and an included bike mount attaches to most road bikes for easy viewing when you're biking at breakneck speeds. An extra-large, scratch-resistant LCD display shows running, cycling, and swimming stats at a glance for quick informational updates so you'll know whether to continue on pace, speed up, or slow down--according to predefined goals and previous efforts. Four unique graphical training modes allow you to surpass predefined goals, stay on pace, count laps, and race against previous bests. Goal mode sets a predetermined goal based on metrics like time, distance, or calories burned. The watch will keep you on track by indicating progress with a pop-up alert when you've eclipsed 50%, 90%, or 110% of your preset goal. Laps mode counts laps based on time, distance, or manual settings that can be defined by the user. This is useful when you're running and swimming a large number of laps (it's easy to lose track). Zones mode creates a target zone based on heart rate (heart rate monitor sold separately) or pace. You'll receive alerts based on your current performance versus the set target, and a user-defined buffer allows you to adjust the target zone plus or minus a set amount for those with less-rigid exercise expectations. Race mode virtually pits you...
