Product Description

The Polar RCX3 Run Heart Rate Monitor is the ideal training partner for recreational runners looking for guidance and feedback on their performance. The RCX3 Run includes the Polar s3+ stride sensor which enables the recording of various valuable training data including:

Speed/Pace – current, average and maximum
Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor. Pace (expressed as min/km or min/mile) stands for the rate of speed. Pace is usually used in running. By setting a target pace, you can follow how fast you need to run in order to reach a certain distance in a predefined time.

Running Index
Running Index is based on heart rate and speed data measured during the run. It gives daily information about your performance level, both aerobic fitness and running economy. Improvement in running efficiency indicates improved economy of running performance.

Cadence – average and maximum

Average stride length
Stride length is the average length of one step, that is, the distance between your right and left foot contacting the ground. Runners adjust stride length to gather speed: stride length increases as speed increases. Yet one of the most common mistakes novice runners make is over-striding. The most efficient stride length is the natural one – the one that feels most comfortable.

Distance – training, lap, trip and total
Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.

The RCX3 Run also has a wealth of smart features to guide you through workouts and provide feedback on your performance including Training Benefit which gives you instant motivating feedback after your session, so if you want to know the effect of different training sessions, this feature will tell you exactly what you need to know.

The Polar fitness test shows you exactly how your fitness is developing. Smart Calories will let you know how many calories you have burned and training Load helps you find the perfect balance between rest and training.

Endurance training programs are downloadable free from polarpersonaltrainer.com with the Polar DataLink to improve your performance while ZoneOptimizer helps you train at the right intensity with personal sport zones.

The Polar RCX3 Run Heart Rate Monitor computer comes complete with a Polar H3 heart rate sensor, Polar s3+ stride sensor, Polar DataLink data transfer unit, RCX3 Getting Started Guide and s3+ stride sensor User Manual. Available in black or white.
