To celebrate the upcoming release of the Spanish version of ‘Getting Started’, I’m planning to update the cover of the English version too. This text (on the green background) will be on the back cover of the books (in the appropriate language) and in the book blurb on reseller websites.

This week, I’m posting about each of the ‘Power =’ items 🙂

Power identifies training targets, based on your fitness, that maximise training results while minimising over-training and risking injury, enabling consistent, uninterrupted progress toward your target event.

This raises two questions:

1. How does power maximise training results?
2. How does power minimise over-training and risking injury?

𝐇𝐨𝐰 𝐝𝐨𝐞𝐬 𝐩𝐨𝐰𝐞𝐫 𝐦𝐚𝐱𝐢𝐦𝐢𝐬𝐞 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐫𝐞𝐬𝐮𝐥𝐭𝐬?

Power enables more precise training targets, using targets relative to your Threshold Power (your current fitness) and that are often just a narrow range of a few percentage points of your Threshold Power.

Which means:
✅ power targets are easier to achieve than pace or HR targets – just ‘run to the numbers’
✅ you’re more likely to target the specific adaptations needed for your goal race
✅ as your fitness improves, your targets automatically adjust to match your increased capability

In other words, Power = Productive Training.

Power calculates a Stress Score for each completed workout, based on the workout’s duration and range of intensities.

These scores can be combined (using research-backed maths) to provide a number of metrics used to monitor your Training Load – the cumulative impact of your training on your body.

The three most important are:
✅ a Training Load Balance, indicating the current balance between shorter-term and longer-term training impacts, so your training can maintain a productive balance between the two
✅ a Ramp Rate, indicating how quickly your training is adding load, so that you can add load safely
✅ a Training Intensity Distribution, showing how much time you’re spending at different intensities, to target the right mix of training for your upcoming event

By maintaining a productive balance, adding load safely and precisely targeting the right mix of intensities, you can:
⚡ maximise your training results, and,
⚡ minimise your risk of over-training and injury.

Which means consistent, uninterrupted progress toward your upcoming event.

𝐏𝐨𝐰𝐞𝐫 = 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐯𝐞 𝐓𝐫𝐚𝐢𝐧𝐢𝐧𝐠

Power identifies training targets, based on your fitness, that maximise training results while minimising over-training and risking injury.

Which raises two questions:

1. How does power identify your running fitness?
2. How does power set training targets based on your fitness?

𝐇𝐨𝐰 𝐝𝐨𝐞𝐬 𝐩𝐨𝐰𝐞𝐫 𝐢𝐝𝐞𝐧𝐭𝐢𝐟𝐲 𝐲𝐨𝐮𝐫 𝐫𝐮𝐧𝐧𝐢𝐧𝐠 𝐟𝐢𝐭𝐧𝐞𝐬𝐬?

Second-by-second as you run, power provides numbers representing your effort.

With a few maximum effort runs (no lab testing needed), you can identify your Threshold Power.

Threshold Power is an important representation of your current running fitness.

𝐇𝐨𝐰 𝐝𝐨𝐞𝐬 𝐩𝐨𝐰𝐞𝐫 𝐬𝐞𝐭 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐚𝐫𝐠𝐞𝐭𝐬 𝐛𝐚𝐬𝐞𝐝 𝐨𝐧 𝐲𝐨𝐮𝐫 𝐟𝐢𝐭𝐧𝐞𝐬𝐬?

Power uses your Threshold Power as an anchor, positioned at 100% on a scale from 60-65% (no longer walking) up through 200% (short sprints) and beyond.

For example, you might use the following training targets:
🔹 80% or less for an easy run
🔹 94-96% for 10-20 minute intervals at half-marathon power
🔹 102-105% for 3-minute VO2max intervals

And if (when) your fitness improves and your Threshold Power increases, your workout targets adjust to match the new anchor, matching your increased fitness.

VO2max is a measure of your body’s maximum aerobic capacity. Threshold Power is the highest intensity you can maintain without rapidly fatiguing and needing to slow down or stop.

Think of VO2max as ‘the size of your engine’, and Threshold Power as ‘your highest cruising speed’. A bigger VO2max means you could go further and faster, but it doesn’t mean you’ll use that capacity effectively; a higher cruising speed means you can travel faster for a sustained period of time.

Both are important, but of the two, threshold power is more actionable, and a more direct and practical predictor of endurance performance.

𝐈𝐬 𝐢𝐭 𝐨𝐧𝐥𝐲 𝐚𝐛𝐨𝐮𝐭 𝐭𝐡𝐞 𝐧𝐮𝐦𝐛𝐞𝐫𝐬?

No.

Training is much more than actions driven by numbers. But training should also be underpinned by quantitative data – and power can provide those numbers.
