The Polar S625X provides runners, triathletes, and coaches with a complete tool to measure performance and workout intensity. With the optional cycling and power sensors and enhanced training tools like the Polar OwnOptimizer recovery test, plus altitude and ascent for route profile, the S625X lets you cross train and put the power of information to work for you. It includes the S1 foot pod, a shoe-mounted sensor that continually relays computed velocity and distance information to a specially-adapted, wristwatch-based display. You’ll be able to get data on total speed and distance, speed displayed in pace or kmph/mph as well as a distance-based interval timer.
It comes with the S625X wrist receiver, a transmitter that’s worn comfortably around your chest, and an elastic strap to hold the transmitter in place. The wristwatch-like receiver features a large display that includes 12/24-hour time of day, alarm, and stopwatch. It provides readings of maximum heart rate of total exercise, average/maximum heart rate of each lap, recovery measurement (by either heart rate divided or time), and interval timers.
You can also better assess your training data using the included Polar Precision Performance (PPP) 4.0 software when you transfer data from the monitor to the PC via a wireless infrared (IR) connection. This feature requires a PC with an IR window or you will need a separate Polar IR interface.
The OwnCal feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. It also allows you to set daily and weekly exercise goals in terms of calorie expenditure. The OwnIndex feature will determine your fitness level, track your improvements, and provide motivation. Polar’s OwnCode technology blocks unwanted signals from other heart rate monitors, ensuring disturbance-free transmission of your heart rate data.
The S625X’s visual and audible alarms alert you when you reach your target heart rate zone. The Time in Target Zone feature calculates the percentage of maximum heart rate or beats per minute in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your exercise program.
Feature Detail:
- Displays your heart rate as beats per minute and percentage of maximum heart rate, average heart rate, and exercise duration
- S1 foot pod shoe-mounted sensor that continually relays computed velocity and distance information to monitor
- Runners’ data including total speed and distance, speed displayed in pace or kmph/mph
- Wirelessly sends exercise data to PC via infrared connection
- Allows you to set 5 exercise sets for interval training with HR target zones and recovery calculation
- Records a complete file and five summary files of the exercises
- Predicts your maximal oxygen uptake
- Reduces possible interference from other heart rate monitors

This is the third polar product I have bought, no problems with the first two. THe 625 X is a real training computer, when it works. Initially everything worked fine, but when the foot pod started asking for battery replacement the problems began. First was the foot pod’s on/off switch, got broken. I sent it to the Service Center and got repaired, but stop working again a week later. Then I sent it to the Warranty Center and told me they would send a new one, got the same one, with the same malfunction. Called Customer Service, and after 20 minutes waiting on the line they suggest to replace the battery, no luck. Will keep trying.

The Polar S625X Heart Rate Monitor is no doubt a technical marvel for serious racers and their coaches. It has many training and record-keeping capabilities that can be shared with your coach.
That’s not me. I like to run and bike for exercise and keep records of how I do. This unit is way too complicated for me and the documentation is soooo bad that I got to page 60 before I figured out how to run with my time and heart rate displayed. I still can’t get a reasonable record of the distances I run, my heart rate or the temperature and altitude.
If you are training for the Olympics and your team has a good technical support person, buy it. Otherwise, save $150 and get something cheaper.

This is the best training option from Polar. You find here 90% of what do you need to run or ride looking for fitness improvement or serious training. The IR interface is nice. Once the watch itself is a little bit bulk is not a good option if you want it to daily use wearing shirts for example.

The Polar 625X Running Computer is simply Awesome. I bough this watch about a year ago and I love it.
Once you star using it, you will be so hooked-up to all the useful information you receive during your running, walking, or any kind of training or workout that you embrace, that will never go out again without it.
Its the perfect complement to your desire to get in shape, improve your health or competitive level.
The watch is easy to use, especially if you have owned a Polar Heart Rate Monitor before. This model comes with the Polar food pod (a small device that you install in your shoe laces to measure distance and speed), the transmitter (this is the device with the chest strap), and a computer software that allows you to view, in a graphic representation, important information for each workout (Heart Rate, Pace, Distance, Speed, Temperature, and Elevation).
As soon as you star training and exercising with this magnificent watch, you feel as if you have a coach or a training partner with you.
If you are an athlete, an enthusiastic runner, a hobbyist, or just conscious about your shape and health, you will definitely love this watch. I do. I have owned different HRM from Polar, and without any doubt this is the very best for running.
This powerful running computer enables you to record personal performance, running and cycling data plus training conditions like altitude or temperature, then analyze your performance when you download via Infrared technology directly to your PC using the included Polar Precision Performance (PPP) 4.0 software. You’ll get total feedback on your training sessions by reviewing a variety of graphical summaries, trends and analysis on the computer. I really love the software, I believe the Polar Precision Performance (PPP) 4.0 software alone is well worth the price of this set.
Train and rest in the right balance. The OwnOptimizer test tells you whether you have recovered enough for your next training session. Based on the test, you are provided with a nice-scale description of your personal training status.
The OwnCal feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. It also allows you to set daily and weekly exercise goals in terms of calorie expenditure. The OwnIndex feature will determine your fitness level, track your improvements, and provide motivation. Polar’s OwnCode technology blocks unwanted signals from other heart rate monitors, ensuring disturbance-free transmission of your heart rate data.
Additionally you could add the bike mount (it’s really inexpensive, I got it for about 6 US$), an accessory that will allow you to take advantage of s625x running computer functionality when training in your bike. You install the bike mount on the handlebar and you are ready to wrap your watch around the bike mount. Now you will be able to follow your heart rate as you go on the road with your bike. The s625x offers the ability to enter two different wheel sizes, enabling you to train on two different bikes.
Prepare yourself to atart getting the best results from your training.
