Racing your personal best

A power rhyme based on 'for want of a nail'

𝐑𝐚𝐜𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐩𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐛𝐞𝐬𝐭

A truth: power isn’t a guarantee that you’ll run a Personal Best (PB) at every race.

So what does ‘racing your personal best’ mean?

𝐏𝐨𝐰𝐞𝐫 𝐢𝐬 𝐩𝐞𝐫𝐬𝐨𝐧𝐚𝐥

It’s a system of metrics based on you as you are right now – your ability, your current fitness, your current form.

Your power metrics are calculated from your completed workouts (for better or worse).

From what you’re able to do.

Right Now.

👉🏼 Power is Personal.

𝐑𝐚𝐜𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐛𝐞𝐬𝐭

If it’s personal to you, how does that translate into racing your best?

Power enables identification of your current running fitness – your Threshold Power.

👉🏼 Which means you’re starting from a known position.

It bases your training targets on your Threshold Power, with incremental progressions (in volume or intensity) to improve your fitness while minimising injury risk.

👉🏼 Which means you can focus on consistently completing planned workouts.

It provides metrics to monitor your changing fitness and your training load, based on your Threshold Power and your completed workouts.

👉🏼 Which means you can adjust your plan if needed (rather than blindly following it).

It uses your training load metrics to plan your taper (more on that in a future post).

👉🏼 Which means you minimise missed training and arrive at the start line with fresh legs, ready to run.

It bases your race day power target on your most recent metrics

👉🏼 Which means you’re running based on you – your race-day fitness, ability, and form.

Power provides a complete system that prepares you to race your best – the rest, as they say, is up to you.

Racing your personal best

Maximising your training

A power rhyme based on 'for want of a nail'

𝐌𝐚𝐱𝐢𝐦𝐢𝐬𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠

Your training begins with a goal.

Your goal should translate into a plan for the workouts you’ll run, including target intensities and durations for each.

And then while executing your plan, you should:
🔹 monitor your fitness – to confirm improvements
🔹 monitor your training load – to ensure you maximise training benefits and minimise injury risk

How does power support this approach?

𝐖𝐨𝐫𝐤𝐨𝐮𝐭 𝐭𝐚𝐫𝐠𝐞𝐭 𝐢𝐧𝐭𝐞𝐧𝐬𝐢𝐭𝐢𝐞𝐬

Power enables more precise training targets, using targets relative to your Threshold Power – your current fitness.

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

𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐟𝐢𝐭𝐧𝐞𝐬𝐬

This is as simple as monitoring:
your Power-Duration Curve – improvements should move your PDC up, to the right, or both
your Threshold Power – which, for many runners, will increase as you get fitter

𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐥𝐨𝐚𝐝

Power provides three key metrics (based on completed or planned workouts) to monitor your training load:
Training Load Balance – indicating whether your training is productive.
Ramp Rate – to avoid adding training load too quickly.
Training Intensity Distribution – to check that your training intensity mix matches your goal race.

Power provides a complete system for maximising your training.

There’s magic in the numbers

A power rhyme based on 'for want of a nail'

𝐓𝐡𝐞𝐫𝐞’𝐬 𝐦𝐚𝐠𝐢𝐜 𝐢𝐧 𝐭𝐡𝐞 𝐧𝐮𝐦𝐛𝐞𝐫𝐬

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

Why’s that important?

Once you can measure your effort, you can answer all sorts of questions.

Here’s a sample …

… 𝐡𝐨𝐰 𝐟𝐢𝐭 𝐚𝐦 𝐈?

Your Threshold Power is a key measure of your current running fitness.

It’s used to set training targets, to monitor training load, and to set race/event goals.

… 𝐚𝐫𝐞 𝐦𝐲 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐚𝐫𝐠𝐞𝐭𝐬 𝐜𝐨𝐫𝐫𝐞𝐜𝐭?

Your training targets are based on your Threshold Power (your running fitness) – what you can achieve right now.

They ensure your targets are ‘just right’ for you, and they self-adjust when your Threshold Power changes.

… 𝐡𝐨𝐰 𝐡𝐚𝐫𝐝 𝐰𝐚𝐬 𝐭𝐡𝐚𝐭 𝐰𝐨𝐫𝐤𝐨𝐮𝐭?

Training Load Scores combine ‘how hard?’ and ‘how long?’ for each completed workout.

They represent the workout’s metabolic stress – its impact on your body.

… 𝐚𝐦 𝐈 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐨𝐨 𝐦𝐮𝐜𝐡? 𝐭𝐨𝐨 𝐥𝐢𝐭𝐭𝐥𝐞?

Your Training Load Balance, calculated from your Training Load Scores, shows whether your training is ‘productive’ – not too much, not too little.

… 𝐚𝐦 𝐈 𝐫𝐚𝐦𝐩𝐢𝐧𝐠 𝐮𝐩 𝐭𝐨𝐨 𝐪𝐮𝐢𝐜𝐤𝐥𝐲?

Your Ramp Rate, calculated from your Training Load Scores, shows if you’re adding training load too quickly, replacing ‘the 10% rule’ with a metric based on ‘how hard?’ and ‘how long?’

… 𝐡𝐨𝐰 𝐡𝐚𝐫𝐝 𝐬𝐡𝐨𝐮𝐥𝐝 𝐈 𝐫𝐮𝐧 𝐨𝐧 𝐫𝐚𝐜𝐞 𝐝𝐚𝐲?

Race-power planning identifies an effort level you can sustain from start to finish, one that will give you the best result you’re capable of.

… 𝐡𝐨𝐰 𝐜𝐚𝐧 𝐈 𝐫𝐮𝐧 𝐟𝐚𝐬𝐭𝐞𝐫?

By working on your form (how you run), you can improve your Running Effectiveness – how effectively you convert effort into speed.

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

All of these metrics are available when Running with Power.

Power is a complete system

A power rhyme based on 'for want of a nail'

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 represents 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

These are inversely related (higher power = shorter duration; lower power = longer duration).

Best effort and maximum effort runs can determine how long you can 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 the training load from each workout – 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

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.

This is part of a series of posts on runners’ feedback about Running with Power.

Based on survey responses and book research, here’re the top three pieces of advice that runners using power would give to those not yet using it.

𝐋𝐞𝐚𝐫𝐧 𝐭𝐡𝐞 𝐟𝐮𝐧𝐝𝐚𝐦𝐞𝐧𝐭𝐚𝐥 𝐜𝐨𝐧𝐜𝐞𝐩𝐭𝐬

There are a few fundamental concepts that form the foundation for understanding power. They’re not difficult to learn and learning them really helps understand how to make the most of running with power.

𝐔𝐬𝐞 𝐚 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐩𝐥𝐚𝐧 𝐝𝐞𝐬𝐢𝐠𝐧𝐞𝐝 𝐟𝐨𝐫 𝐩𝐨𝐰𝐞𝐫

The Palladino plans were frequently mentioned, with targets matched to how the body works, incremental progression and built-in power tests. They improve your fitness without you noticing, while reducing the risk of injury or overtraining.

On a related point, power works best when training for an event. If all you ever do is run easy, or run with friends, then Running with Power isn’t for you.

𝐓𝐫𝐮𝐬𝐭 𝐢𝐧 𝐭𝐡𝐞 𝐩𝐫𝐨𝐜𝐞𝐬𝐬

Just start by wearing the footpod (or turning on wrist-based power). Later, start looking at the metrics and, combined with learning the concepts, begin to understand what your data is showing you about your training.

𝐎𝐭𝐡𝐞𝐫 𝐚𝐝𝐯𝐢𝐜𝐞

There was other advice offered by runners using power, including: it helps you learn about your body and your capabilities; keep your Threshold Power updated (it’s a basic for accurate targets & planning); it helps if you like working with data and numbers; power helps maintain training consistency; use power to calibrate your perceived effort

Based on survey responses and book research, here are the top three difficulties runners experienced using power.

𝐆𝐞𝐭𝐭𝐢𝐧𝐠 𝐒𝐭𝐚𝐫𝐭𝐞𝐝

There is a learning curve associated with using power – some fundamental concepts that power is based on, and some things you should and shouldn’t do. However, these are well-known, documented and often discussed in the power-focused Facebook groups – it just takes time.

The setup can also be quite complicated – whether you’re using Stryd or using wrist-based power. With a little patience, it’s possible to end up with a watch setup and supporting application setup that work well. It’s just harder than the setup needed to run using pace or heart rate.

𝐌𝐚𝐢𝐧𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐚 𝐯𝐚𝐥𝐢𝐝 𝐓𝐡𝐫𝐞𝐬𝐡𝐨𝐥𝐝 𝐏𝐨𝐰𝐞𝐫

There are three commonly-used test protocols, all of which produce a usable Threshold Power number. But they all rely on maximum effort runs – and it’s this aspect that runners found difficult. Fortunately for most runners, max-effort runs, while always difficult, got easier to execute with practice.

𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 𝐭𝐨 𝐫𝐮𝐧 𝐮𝐬𝐢𝐧𝐠 𝐩𝐨𝐰𝐞𝐫

Many runners were already be used to running using pace, HR or perceived effort. They reported that it took time to fully trust power, and to stop relying on the other metrics.

𝐎𝐭𝐡𝐞𝐫 𝐝𝐢𝐟𝐟𝐢𝐜𝐮𝐥𝐭𝐢𝐞𝐬

There were other difficulties runners experienced using power, including: using power in mountainous, windy or other ‘unusual’ environments; that power represents your effort (rather than actually being your effort, like cycling); that it was easy to forget (or forget to charge) the pod; that it was difficult to explain to others.

That said, power is still relatively new – we can expect further changes and improvements moving forward!

This is part of a series of posts on runners’ feedback about Running with Power.

Based on survey responses and book research, here are the top three benefits runners experienced using power.

𝐀𝐛𝐥𝐞 𝐭𝐨 𝐭𝐫𝐚𝐢𝐧 𝐭𝐨 𝐭𝐚𝐫𝐠𝐞𝐭𝐬

Sounds simple? Yet with power, according to the feedback, it’s much easier to do. First, the targets are numbers or number ranges, rather than ‘10k pace’ or ‘zone 2’ (when your heart rate seems determined to stay in zone 3). Second, they’re based on your current fitness, adjusting as you get fitter. Finally, you just have to run to effort, which changes to match your route, however hilly it might be.

𝐂𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐜𝐲

The #1 goal of training – being able to follow the plan without getting injured. Training to targets matched to individual fitness gave runners confidence in the plan, allowing them to ‘relax’ and enjoy the experience. And with plans written to add training load slowly and carefully, runners experienced a powerful feedback loop – clear targets => able to run to target => confidence in the plan => increasing fitness without injury => targets adjust to match fitness => able to run to target…

𝐈𝐦𝐩𝐫𝐨𝐯𝐞𝐝 𝐫𝐚𝐜𝐞-𝐝𝐚𝐲 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞

Power offers a couple of race planners, both of which produced power-based targets for races and events that were not only achievable, but for many runners, accurate to within a few watts, and to within a minute or two (over a marathon).

But it was at the start that power was most beneficial, providing a target that prevented runners from starting too fast (given the excitement and the ‘freshness’ that’s usually present at the start of many events).

𝐎𝐭𝐡𝐞𝐫 𝐫𝐞𝐚𝐬𝐨𝐧𝐬

There were many other benefits runners experienced using power, including: being able to measure fitness improvements; power is responsive, matched to effort; gaining a better understanding of their physiology and capabilities; finding a great community of runners all learning how best to use power.

This is part of a series of posts on runners’ feedback about Running with Power.

Based on survey responses and book research, here are the top four reasons why runners started using power.

𝐈𝐭’𝐬 𝐣𝐮𝐬𝐭 𝐨𝐧𝐞 𝐧𝐮𝐦𝐛𝐞𝐫

The most popular reason – power gives you one number that changes as your effort changes. And it represents your effort when on the flat, up and down hills, or running in wind. You can even adjust for running in heat, high humidity or at altitude. You just need to ‘run to the number’.

𝐏𝐚𝐜𝐞 𝐚𝐧𝐝 𝐡𝐞𝐚𝐫𝐭 𝐫𝐚𝐭𝐞 𝐰𝐞𝐫𝐞𝐧’𝐭 𝐰𝐨𝐫𝐤𝐢𝐧𝐠

Whether it was because of pace issues on hilly routes, heart rate lags when starting or stopping intervals, or not being able to accurately judge effort, runners were having difficulties using other methods of measuring how hard they were running.

𝐓𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐡𝐚𝐭 𝐰𝐨𝐫𝐤𝐬

Many non-power plans come with a risk of overtraining or leaving potential training gains unrealised. Power uses narrower target ranges within zones, and the power-based plans from Steve Palladino have worked for hundreds of injury-free runners.

𝐁𝐞𝐭𝐭𝐞𝐫 𝐫𝐚𝐜𝐞 𝐫𝐞𝐬𝐮𝐥𝐭𝐬

Runners were looking for a way to improve their race results, qualify for Boston (or similar), or to find a way to improve their race pacing. While power can’t guarantee better results or a qualifying time, race planning with power uses current fitness, stamina and running effectiveness to determine personalised race targets.

𝐎𝐭𝐡𝐞𝐫 𝐫𝐞𝐚𝐬𝐨𝐧𝐬

There were many other reasons why runners started using power, including: power is based on physiology; it’s backed by years of research (from cycling and running); it uses data-driven insights; it can be used on a treadmill or in bad GPS locations.

Feedback from runners using power

Runner feedback (depicted as a green thumbs up and a red thumbs down)

𝐅𝐞𝐞𝐝𝐛𝐚𝐜𝐤 𝐟𝐫𝐨𝐦 𝐫𝐮𝐧𝐧𝐞𝐫𝐬 𝐮𝐬𝐢𝐧𝐠 𝐩𝐨𝐰𝐞𝐫

A few weeks ago, posts outlined reasons you might choose to use power to measure how hard you’re running.

This week, posts will cover this in a little more depth, exploring the following questions:
❓ Why did you start running with power?
❓ What benefits have you experienced?
❓ What difficulties have you experienced?
❓ What advice would you give to someone not yet Running with Power?

The posts will summarise the top themes from feedback received when asking runners these questions – feedback from two annual surveys, and feedback gathered while researching two of my books (‘Why’ and ‘Getting Started’).

Here are my answers to those questions.

𝐖𝐡𝐲?

I wanted to break sub-4 for the marathon and found training using pace or heart rate difficult in several ways. Power (training using effort) just made sense to me … plus, I like working with data and metrics.

𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬?

There’s magic in the numbers – as a runner using power, I can: measure (and track) my fitness; set precise workout targets; monitor my training load; set achievable race-day targets.

As a coach, power makes it possible to set workout goals that I know will be usable whatever route my runners choose to take (hilly or not). And the insights that are possible using power data make fine-tuning (or course-correcting) so much easier.

𝐃𝐢𝐟𝐟𝐢𝐜𝐮𝐥𝐭𝐢𝐞𝐬?

It was expensive – I bought a running watch and a Stryd footpod. And it was difficult to use, although the Stryd PowerCenter these days is light years ahead of where it was when I first started.

While it is now possible to buy a running watch with a power meter inside, it’s complex to calculate power metrics – hopefully that’ll change in the next few years.

𝐀𝐝𝐯𝐢𝐜𝐞?

Go for it. Based on using power since 2018, I firmly believe Running with Power is the most effective way to train.

Why power? Power can measure running form improvements

A runner looking powerful

Want to improve your finish times?

You have two choices:
✅ Work on your fitness – so you can run the event distance maintaining a higher effort than before
✅ Work on your form – so you can run faster for the same effort, run at the same speed for less effort, or both

𝐇𝐨𝐰 𝐝𝐨 𝐲𝐨𝐮 𝐰𝐨𝐫𝐤 𝐨𝐧 𝐲𝐨𝐮𝐫 𝐟𝐨𝐫𝐦?

You can work on your form using drills, plyometrics, strength and conditioning, mobility and other supplemental work.

𝐇𝐨𝐰 𝐜𝐚𝐧 𝐲𝐨𝐮 𝐦𝐞𝐚𝐬𝐮𝐫𝐞 𝐟𝐨𝐫𝐦 𝐢𝐦𝐩𝐫𝐨𝐯𝐞𝐦𝐞𝐧𝐭𝐬?

Running Effectiveness (RE) measures how effectively you convert power into forward motion.

It’s calculated as the ratio of speed to power = speed / power.

RE is 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.

Measure your RE before beginning your form work, then again at the end, comparing the results to see if you’ve made a positive difference to your Running Effectiveness.

𝐑𝐄 𝐜𝐚𝐧 𝐛𝐞 𝐚 𝐝𝐢𝐟𝐟𝐢𝐜𝐮𝐥𝐭 𝐦𝐞𝐭𝐫𝐢𝐜 𝐭𝐨 𝐦𝐞𝐚𝐬𝐮𝐫𝐞

Why?

It’s affected by: your power meter; your weight; how hard you’re working; hills; wind; running shoes.

One way to track RE improvements is to use reference runs.

Every 3-4 weeks, run the same route at the same target intensities wearing the same running shoes.

Reference runs provide an opportunity to compare RE from one run to the next, so that you can see if you’re improving.
