Power is a complete system

Power is a complete system

It’s a system built on your individual capabilities.

And it has five fundamental concepts that work together to enable you to run your personal best.

Power = Effort

Power numbers represent your effort, so you can see how hard you’re working while running and how that changes as you run (whether you decide to make the change, or hills or wind force you to change your effort).

Threshold Power

Threshold is a small range of effort levels, below which you can run at a steady effort, and above which you fatigue much more quickly and will need to slow down or stop.

Threshold Power is used to set training targets, to monitor training load, and to set race/event goals.

Power-Duration

Power and Duration are inversely related (higher power = shorter duration; lower power = longer duration).

Best effort and maximum effort runs are used to estimate how long you could sustain differing effort levels, giving you a view of your current capability over a range of intensities.

Training Load

Training Load Scores combine ‘how hard?’ and ‘how long?’ and represent each workout’s metabolic stress – its impact on your body.

You can combine the scores to calculate metrics you can use to monitor whether your training is productive (not too much, not too little), and to manage injury risk.

Running Effectiveness

Running Effectiveness is a speed:power ratio that you can use to estimate finish times, to assess changes to your running form and to evaluate your fatigue resistance.

Power is a complete system

It has metrics showing your fitness, your ability over a range of intensities, whether your training is effective while minimising injury risk, and targets that you can use to run your Personal Best on race-day.

And all of these metrics are based on you, on what you can do, not on averages from thousands of other runners who aren’t you.
