To achieve your full potential you need to know when you should be running and when you should be resting.

"The most important day in any running program is rest. Rest days give your muscles time to recover so you can run again. Your muscles build in strength as you rest." Hal Higdon, Editor, Runner's World

How will you determine how far or fast to run today? How do you decide how often you should run?

Overtraining frequently results in injury, illness and diminishing performance. Measurement and monitoring of recovery will enable runners to train smarter, preventing overtraining. The body can endure just so much continual physical stress before it begins to breakdown, leading to frequent colds, coughs, and complications such as runner's knee, hamstring injuries and stress fractures.

Training = Running + Recovery

Many runners measure workouts precisely in hours or distance run but recovery only in subjective measurements such as feelings of tiredness and soreness of legs. Only the best runners measure their recovery effectively, with tools such as ithlete.

So How do You Know When to Run and When to Rest?

Runners "Please avoid training too hard and 'overtraining'. Train Smart."
Uta Pippig, World Renowned Runner

The answer is ithlete, which measures the time gap between your heartbeats when you're resting. Measuring heart rate variability (HRV) with ithlete enables runners to determine their training/running readiness. The heart speeds up when you inhale, and slows down when you exhale; the time difference is known as HRV. A healthy, well rested body will produce a wider gap than a stressed out, over trained body.

Measuring HRV with ithlete is not unlike the morning ritual of taking a resting heart rate. Research has shown that measuring and tracking HRV presents a more precise picture of your overall health, to determine fatigue, overtraining or approaching illness.

Convenient, Informative, Inexpensive: ithlete


Previously used solely by a small group of elite athletes and their coaches HRV was time consuming, expensive and difficult to track. Until now; ithlete makes measuring and tracking HRV convenient and affordable for runners.

User friendly and intuitive ithlete means runners can now measure and interpret HRV themselves, and in only 60 seconds. A signal is sent from your chest strap monitor to a small receiver which attaches to your smart phone or tablet.

The app displays a colour coded graph of your HRV score as well as a train/train easy/rest recommendation, enabling you to get the most from your run and avoid injury. A high reading combined with a normal resting pulse is good news - you can train hard that day. A low reading means you should take it easy, providing you with a guilt free rest or lighter intensity day. And while your body is in recovery mode, your muscles are busy getting stronger.

Runners can now record both their training load and any comments to further enhance the meaningful data provided by ithlete. Progress over time is conveniently displayed in both graphical and numerical format by ithlete, enabling runners to prepare for events and continue to increase fitness and performance.

All you need to get started today is a compatible chest strap, ithlete receiver and ithlete HRV app; and all for less than the price of a pair of running shoes!


HRV Monthly Chart Explained...

Amber lines occur after intensive workouts and indicate the need for extra rest and recovery. Green lines occur when the body has recovered well. White lines indicate normal HRV levels. Blue lines show the overall trend and moves upwards significantly during the final week of this chart, when little exercise was performed.

Today's HRV number is displayed at the top of the screen. Unlike resting pulse, a higher number is better.

The three coloured indicators at the top right show the amount of change in HRV that has occurred over the past day, week and month. The Daily Change is used as a traffic light for training, whereas the week and month indicators show positive or negative trends.
