At some point or another, you’ve been told by your training plan, smartwatch or coach to train by effort, pace and or heart rate. But have you stopped to consider if one is better than the other? If so, does the situation matter when you use the one or the other?

 Is there another thing that you might not know about that could be even better?

 You’re in luck because in this episode which you can listen to by clicking the above video or below audio podcast, you’ll find the answers to all of those questions and more.

But in this post, let’s focus on going deep and unpacking my “Mindful Metrics Run Prism” approach to better running.

The Triangular Approach to Smarter Running

Let me introduce you to a method I developed during one of my races: the Mindful Metrics Run Prism. I was in a bit of a suffer slump, and my mind decided to create a framework for analyzing that race. This framework combines effort/power, pace/speed, and intelligence to create a balanced approach to training and racing.

The Effort and Power Axis (Input)

Effort is something every runner understands intuitively. It’s the feel of the run, the subjective measure of how hard you’re pushing yourself on a scale of 1 to 10. Power, on the other hand, offers an objective input measure. Using a power meter, you can quantify the watts you’re producing, providing a consistent metric regardless of external conditions like terrain or weather.

During that hard race, I realized the synergy between effort and power. Running up a steep hill, my perceived effort felt like a 5 out of 10. Yet, when I looked down at the power metric on my watch, I saw my output spiked to 370 watts. This was much higher than the 330 watts I aimed to hold as an average through the race. This discrepancy made me adjust my pace to align my subjective effort with the objective power data. By doing so, I could maintain a steady effort without overexerting myself early on.

Something interesting also happened on the long hill efforts. When I started out on a hill, I wanted to keep my power at my average of 330 watts, but the hill had spikes and flat spots. This made holding exactly 330 watts quite difficult. At the start, it felt like I was going quite slow. The hill was about eight minutes (1.2 miles/1.8km), but at the end of the hill, my effort started feeling closer to a 7/8 out of ten, and the power average was 330 watts even though it would get as high as 350 watts and as low as 280 watts depending on the gradient.

Pace/Speed: Output That You Can’t Control

Pace or speed is often seen as the ultimate measure of a runner’s performance, but it can be misleading due to factors beyond your control, such as terrain and weather conditions. While pace is a useful metric for certain workouts and parts of the race, it should not be the sole focus. For instance, during a race, maintaining a specific pace might be impossible due to unexpected hills, temperature or strong winds. Instead, pace should be viewed as the outcome of balancing effort and power.

By integrating pace within the Mindful Metrics Run Prism, you can better understand how external factors influence your speed. Example – if you’re running uphill and your pace drops, knowing your power output and effort level can reassure you that you’re still on track, even if your speed decreases. This frame of mind helps you avoid spiking and ensures that you’re running efficiently, adapting to conditions rather than forcing a specific pace.

Intelligence: The Cornerstone

Intelligence in running isn’t just about smart pacing or knowing when to push hard. It encompasses strategic decisions based on real-time data and race conditions. During the same race, I was at a critical point, 33% into the course. My initial pace was too ambitious, driven by the adrenaline and excitement of the start. My power meter indicated I was exceeding my sustainable power output. It was a make-or-break moment.

I decided to back down, aligning my original race strategy with my power data. This decision was based in intelligence—understanding my limits and adjusting accordingly. Intelligence also involves post-race analysis, interpreting data to refine future strategies. It’s about learning from each run and continually improving. One percent better, Kaizen.

The Triangular Balance: Effort, Power, and Intelligence

The Mindful Metrics Run Prism is a holistic approach, where each corner—effort/power, pace/speed and intelligence—supports the other. Effort provides the feel; power offers measurable data; pace/speed is the output of what is happening, and intelligence ties it all together with strategic thinking. This triangular balance helps runners navigate the complexities of training and racing, ensuring they don’t rely too heavily on any single metric.

For instance, during downhill segments, maintaining a high power number can be tricky. The natural tendency is to let gravity do the work, but to sustain power, you must increase your effort. This balance ensures you don’t lose momentum and can hit your goal time, leaving as much on the finish line as possible.

Embrace The Triangle

This is a dynamic framework that adapts to various running conditions and individual needs. By combining effort, power, and intelligence, you create a comprehensive approach to running that leverages both subjective feel and objective data. This method not only enhances performance but also promotes smarter, more informed running decisions. Embrace this triangular approach, and you’ll find yourself running not only faster but also smarter.
