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 difficulties runners experienced using power.

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.

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.

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.

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!

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.

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…

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.

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 provides personal best race-day targets

A runner looking powerful

𝐏𝐨𝐰𝐞𝐫 𝐩𝐫𝐨𝐯𝐢𝐝𝐞𝐬 𝐩𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐛𝐞𝐬𝐭 𝐫𝐚𝐜𝐞-𝐝𝐚𝐲 𝐭𝐚𝐫𝐠𝐞𝐭𝐬

Does this mean a new Personal Best (PB) at every event?

No.

Instead, power can identify race-day targets that you can maintain throughout the event to achieve the best result you’re capable of on the day.

How?

𝐓𝐡𝐞 𝐒𝐭𝐫𝐲𝐝 𝐑𝐚𝐜𝐞 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐨𝐫

The Stryd Race Calculator uses your workouts from the last 90 days, your Auto-CP (Threshold Power) and (optionally) information about the event course and the expected environmental conditions to produce a best-case target power and an estimate of your finish time.

𝐒𝐮𝐩𝐞𝐫𝐏𝐨𝐰𝐞𝐫 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐨𝐫 (𝐒𝐏𝐂)

Using your Threshold Power, Running Effectiveness (how well you convert effort into forward motion), a fatigue resistance measure specific to your race distance, and (optionally) the expected environmental conditions, SPC provides race power target scenarios, the equivalent percentage of your Threshold Power and estimates of your finish time.

𝐔𝐬𝐢𝐧𝐠 𝐭𝐡𝐞 𝐫𝐚𝐜𝐞-𝐝𝐚𝐲 𝐭𝐚𝐫𝐠𝐞𝐭

Power-based targets are a little different than you may be used to.

They’re based on you, not on population averages – 𝑦𝑜𝑢𝑟 current fitness, 𝑦𝑜𝑢𝑟 fatigue resistance, and 𝑦𝑜𝑢𝑟 ability to convert power to speed.

They’re a power (or effort) target, not a hopeful goal time – to quote Steve Palladino “your time is determined by the power you 𝑐𝑎𝑛 run, not by the power you ℎ𝑜𝑝𝑒 to run.”

Your Threshold Power is used to …

… 𝐬𝐞𝐭 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐭𝐚𝐫𝐠𝐞𝐭𝐬

Training targets are set as a percentage of threshold for all types of workouts (long runs, intervals etc.)

The percentages vary depending on the purpose of the workout and the ability of the runner. But they all have one thing in common – they are based on your threshold, which means:
🔹 they are based on your current running fitness – what you can achieve right now (without over- or under-training).
🔹 your workout targets self-adjust if your threshold changes

… 𝐦𝐨𝐧𝐢𝐭𝐨𝐫 𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠 𝐥𝐨𝐚𝐝

Training stresses your body and, if done correctly, encourages it to adapt.

Running with Power uses Stress Scores to monitor your training load. Stress scores represent the physical and metabolic stress of each workout.

Stress scores are relative to your threshold, so that if your threshold power changes, stress scores stay aligned to your threshold and to your ability to cope with the training.

… 𝐬𝐞𝐭 𝐫𝐚𝐜𝐞/𝐞𝐯𝐞𝐧𝐭 𝐭𝐚𝐫𝐠𝐞𝐭𝐬

Your threshold is a key measure of your running fitness. On race day, your finish time will depend to a large extent on your running fitness.

To plan your race-day target power based on your race-day fitness, it’s essential to know your threshold power.
