Power is still relatively new for runners. And while there are some apps that cover most of the important metrics, you may find that you need additional apps to plug the gaps.

Here are a few apps that can fill those gaps.

Apple Health doesnโ€™t provide any of the important metrics.

Which means youโ€™ll need to transfer your workout data from Apple Health into an app that can provide these, like WKO or Intervals.icu.

There are a few apps that will do this. Iโ€™ve successfully used HealthFit; other options are RunGap or Health Sync.

The only app to provide this (natively) is WKO.

If youโ€™re a Stryd user, or if youโ€™re using Intervals.icu, youโ€™ll need to calculate RE manually or use SuperPower Calculator for Sheets (SPCs).

Steve Palladinoโ€™s video โ€˜Running Effectiveness and the SuperPower Calculatorโ€™ demonstrates how to use SPCs to calculate RE for a workout or a workout section.

In the following, the term โ€˜Strydโ€™ includes Stryd PowerCenter and Stryd Mobile

โœ… Threshold Power. Stryd uses the term โ€˜Critical Powerโ€™ (CP) and offers an automatically calculated CP (Auto-CP) as well as a manually-set CP (using various protocols).

โœ… Training Load Score. Stryd uses the term โ€˜Running Stress Scoreโ€™ (RSS) and offers a unique calculation which includes a term representing the additional biomechanical stress put on your body from running (vs. cycling).

โœ… Training Load Balance. Stryd uses the term โ€˜Running Stress Balanceโ€™ (RSB) and offers guidance for how to interpret your RSB.

โŒ Ramp Rate. Stryd does not show your Ramp Rate (RR). Youโ€™ll need to calculate RR manually using Strydโ€™s 42d Avg (in Stryd Mobile) or use another system to track this.

โŒ Running Effectiveness. Stryd does not show your Running Effectiveness (RE). Youโ€™ll need to calculate RE manually using another system, or use one of Stryd’s alternate metrics – for example Form Power, Leg Spring Stiffness, Impact Loading Rate.

Power is a complete system using effort as its fundamental metric.

Power uses your second-by-second effort from completed workouts to calculate metrics that build a detailed picture of your running capabilities.

Imagine you run 3 times per week for around an hour each time. Thatโ€™s 60 pieces of data per minute, 3600 per hour and for 3 runs, over 10,000 pieces of data. Thatโ€™s a lot of data!

Which is why power relies on power-aware applications (โ€˜appsโ€™) to calculate your metrics.

โœ… Threshold Power. Represents your current running fitness.

โœ… Training Load Score. A score (per workout) that combines โ€˜how hard?โ€™ and โ€˜how long?โ€™ โ€“ represents the workoutโ€™s metabolic stress, its impact on your body.

โœ… Training Load Balance. Indicates whether your training is โ€˜productiveโ€™ โ€“ enough stress to encourage adaptations, but not so much that there is a greater risk of injury or over-training.

โœ… Ramp Rate. Replaces โ€˜the 10% ruleโ€™ with a metric based on your training load scores โ€“ to monitor whether youโ€™re adding training load too quickly.

โœ… Running Effectiveness. Measures how effectively you convert power into speed โ€“ used to estimate finish times, to assess changes to your running form and to evaluate your fatigue resistance.

There are other criteria that will influence your choice of apps, but being able to calculate these metrics is key.

Running Effectiveness and race planning

There are three primary uses for Running Effectiveness:
โœ… To improve your form
โœ… To improve your fatigue resistance
โœ… To identify targets for your upcoming race

Running Effectiveness can help identify the optimum power target for your upcoming event.

๐‘๐š๐œ๐ž ๐‚๐š๐ฅ๐œ๐ฎ๐ฅ๐š๐ญ๐จ๐ซ๐ฌ

Depending on your choice of power meter and supporting apps, there are two different race calculators you can use to identify your optimum power target:
๐ŸŽฏ If you use a Stryd footpod and the Stryd ecosystem, you can use the web-based Stryd Race Calculator
๐ŸŽฏIf you use wrist-based power, you can use the โ€˜Generate Race Power Scenariosโ€™ feature in SuperPower Calculator (for Google Sheets).

๐‡๐จ๐ฐ ๐๐จ ๐ญ๐ก๐ž๐ฒ ๐ฐ๐จ๐ซ๐ค?

Whichever calculator you use, they work similarly, using (at a minimum):
๐Ÿ”น Your race-day running fitness โ€“ your Threshold Power on race-day
๐Ÿ”น Your fatigue resistance โ€“ one of two different metrics, depending on whether youโ€™re running a shorter, higher-intensity race or a longer, lower-intensity race
๐Ÿ”น Your running effectiveness โ€“ your estimated finish time depends on how effectively you convert power into speed

These metrics are calculated from your completed workouts.

Which means that your training plan should include specific workout segments supporting the race-day calculations.

And it means that Running with Power personalises your race-day target, based on your capabilities, instead of calculating your target using averages from thousands of other runners (who are not you).

You may be familiar with the term stamina, which is similar to, but not the same as fatigue resistance:
โœ… Stamina โ€“ your ability to sustain effort for a longer duration
โœ… Fatigue Resistance โ€“ your body’s ability to resist the effects of fatigue

This post focuses on fatigue resistance, starting with a simple question.

When you fatigue (while running):
๐Ÿ”น youโ€™ll probably slow down
๐Ÿ”น your gait or form may change
๐Ÿ”น you may experience mental sluggishness
๐Ÿ”น you may have an increased risk of injury

According to Steve Palladino, you could focus on metrics that measure gait or form, looking for changes in those metrics over the course of a run.

There are a few metrics heโ€™s investigated. One of them is available with any kind of power meter – Running Effectiveness.

In a FaceBook post, Steve outlines a couple of ways to measure fatigue resistance using higher-intensity sections in long runs.

๐‡๐จ๐ฐ ๐œ๐š๐ง ๐ฒ๐จ๐ฎ ๐ข๐ฆ๐ฉ๐ซ๐จ๐ฏ๐ž ๐ฒ๐จ๐ฎ๐ซ ๐Ÿ๐š๐ญ๐ข๐ ๐ฎ๐ž ๐ซ๐ž๐ฌ๐ข๐ฌ๐ญ๐š๐ง๐œ๐ž?

Itโ€™s one thing to be able to measure fatigue resistance, but how can you improve it?

Through a well-structured training plan.

And to check that your fatigue resistance is improving, you could use reference runs.

RE provides an objective way to assess improvements in fatigue resistance.

Running Effectiveness and form improvements

Your running form is not the same as your running gait:
โœ… gait is the โ€˜whatโ€™ – the movement sequence like heel-striking or lifting your foot
โœ… form is the โ€˜howโ€™ – whether your movements are efficient, stable, and injury-free

By working on your form (how you run), you can improve your running effectiveness.

But itโ€™s not a straightforward thing, and itโ€™s easy to make things worse rather than better.

๐‡๐จ๐ฐ ๐œ๐š๐ง ๐ฒ๐จ๐ฎ ๐ฐ๐จ๐ซ๐ค ๐จ๐ง ๐ฒ๐จ๐ฎ๐ซ ๐Ÿ๐จ๐ซ๐ฆ?

Before starting any form work, consult a sports physiotherapist. They should be able to assess your current form and help you identify whether there are things you should prioritise to reduce injury risk.

A second option is to work with a specialist running coach, someone who has the training and tools to assess your running form and identify things you could do to improve your form.

Both the physio and the running coach will probably suggest activities to add to your training plan โ€“ strength and conditioning, running drills, plyometrics, and other supplemental activities.

Before starting any supplemental activities, complete a reference run or two.

This will provide baseline RE measurements.

Then, while working on your form, complete additional reference runs to track whether the activities are improving your form (and you should continue them), or whether you should try something different.

RE provides an objective way to assess whether form changes are improvements.

Is Running Effectiveness easy to use?

An athlete using drills to improve their form

Running Effectiveness uses speed and power (effort) – both are measurable numbers. RE is easy to calculate.

But Running Effectiveness measures how effectively you convert power into speed, and there are many things that can affect that conversion.

๐‘๐ฎ๐ง๐ง๐ข๐ง๐  ๐ข๐ง๐ญ๐ž๐ง๐ฌ๐ข๐ญ๐ฒ

Differences in your running form at different intensities (jogging vs. running vs. sprinting) will affect how effectively you convert power into forward motion, impacting RE.

๐‡๐ข๐ฅ๐ฅ๐ฌ & ๐–๐ข๐ง๐

When you run uphill, your power will be higher for the same speed โ€“ and your RE will be lower. The reverse is true when running downhill.

The same is true for running into a headwind (lower RE), or with a tailwind.

Running shoes are made from differing materials with differing stack heights. This can affect how effectively you convert power to speed.

There is no agreed standard for calculating running power โ€“ different power meters will produce differing numbers. This means RE (for identical runs) will differ based on the power meter you used.

RE uses power divided by weight. If you change the weight configured for your power meter, RE calculations made before that change will not be comparable with RE calculations made after that change, unless you calculate RE using the weight configured at the time of each run.

RE isnโ€™t so easy to use!

But one way to monitor changes in RE is to use reference runs, a strategy that Fred Richardson (a fellow coach) shared with me.

These are runs you include every 3-4 weeks in your training plan, where you run the same route at the same target intensities in the same running shoes. Reference runs minimise the variations between runs, so that you can compare RE between runs and spot improvements.

What is Running Effectiveness?

An athlete using drills to improve their form

Imagine you want to run a faster marathon or a faster 5k.

You have a couple of choices.

If you’re fitter, you should be able to maintain a higher effort over the event distance.

A higher effort should mean a faster speed, resulting in a quicker finish time.

You can improve your fitness by training, and you can measure fitness improvements by tracking your threshold power.

Rather than improving your fitness, you could work on how you run.

If you’re more effective at converting your effort (power) into forward motion (speed), you can run faster for the same effort, resulting in a quicker finish time.

You can work on how you run (your running form) using drills, plyometrics, strength and conditioning, and other supplemental work.

But how can you measure whether that work has improved your running form?

Running Effectiveness (RE) was proposed by Andrew Coggan, PhD, and measures how effectively you convert power into speed.

Itโ€™s a field-based measure similar to, but different from Running Economy (oxygen consumption at various speeds) or Running Efficiency (external mechanical power vs. metabolic power production), which both require lab-based testing.

RE = speed / power, where speed is in metres per second and power is in Watts per kilogram.

For an easy way to calculate RE from your power meter data, you can use SuperPower Calculator, as demonstrated by Steve Palladino in this video.
