For Triathletes and Cyclists:
The Polar S625x, S725, S720i, and the S520 are heart rate monitors designed specifically for triathletes and cyclists.

At the top of the list is the Polar S625x - which can collect speed and distance data from both cycling and running workouts. It is compatible with all cycling sensors (including the power sensor.) Similar in function is the Polar S725X.

The Polar S720i, and S520 monitors can collect speed and distance on the bike, and heart rate on the run. These monitors all include a speed sensor, all have an optional cadence sensor, and all download your workout data to your computer. The S520 uses a SonicLink (microphone) interface and the others all use the faster and more reliable InfraRed technology.

Runners have four great choices in the S-Series - the S625X, S610, S410 and the S210.

First, for runners looking for a compact monitor with stopwatch features, the S210 is an excellent choice. It's features include: 3 target zones with alarms, 3 countdown timers, intervals, time in/above and below your target zone, and much more!

The S410 offers all of the features of the S210 - plus it lets you download your workout data to the computer using the SonicLink download. By downloading your data, you can automatically record your data in PC Coach software, and see a heart rate graph, which details how your heart responded to the workout over time.
