The Obsession with Pace and Numbers
In the age of fitness trackers, it’s easy to get caught up in the numbers: kilometres per hour, minutes per kilometre, and the golden target of 10,000 steps. We often judge a 'good' walk by how quickly we complete it. While walking faster is linked to better
health outcomes like improved cardiovascular fitness and even longevity, focusing solely on speed can be misleading and unsustainable. A pace that is challenging for a beginner might be a warm-up for a seasoned walker. Factors like terrain, incline, sleep quality, and daily stress levels all influence what your body is capable of on any given day. Chasing a specific number on your watch can lead to frustration or, worse, overexertion and injury if you’re not listening to what your body needs.
A Smarter Metric: Rate of Perceived Exertion
Instead of focusing on external data, experts suggest turning inward to a more personalized metric: the Rate of Perceived Exertion, or RPE. Put simply, RPE is a subjective measure of how hard you feel your body is working during physical activity. Developed by researcher Gunnar Borg, it traditionally runs on a scale from 6 (no exertion at all) to 20 (maximal effort). A more user-friendly version uses a 0-10 scale. This approach accounts for all the variables that a watch can’t measure—your fatigue, your energy, your current fitness level. It’s about honouring that some days a slow walk is all you can manage, while on others, you’ll feel energized and ready to push harder. This makes your fitness journey more intuitive, enjoyable, and ultimately, more effective.
The 'Talk Test': Your Built-In Effort Guide
You don't need a chart to use RPE. The easiest way to gauge your walking intensity is the 'talk test'. Health authorities, including the CDC, recommend this simple method. If you can talk comfortably in full sentences but can't quite belt out your favourite song, you're likely in the moderate-intensity zone. This is the sweet spot for reaping most of the health benefits of walking, such as a lower risk of heart disease, stroke, and type 2 diabetes. If you can only manage a few words before needing to pause for breath, you’ve moved into vigorous intensity. If you can sing with ease, your effort is light. The talk test is a free, reliable tool that’s with you on every walk, helping you find the right level of effort for your body, on that specific day.
Why 'Moderate Intensity' Is the Goal
Most health guidelines recommend about 150 minutes of moderate-intensity aerobic exercise per week for adults. Walking at a moderate intensity—a level that feels somewhat hard—is what strengthens your heart and lungs, improves blood pressure, helps regulate blood sugar, and boosts brain function. While a gentle stroll is certainly better than being sedentary, it's the sustained, moderate effort that triggers the most significant physiological adaptations. By focusing on achieving that feeling of moderate exertion for about 30 minutes, five days a week, you ensure you are doing enough to positively impact your long-term health. This approach shifts the goal from covering a certain distance to accumulating a certain quality of effort.
Putting It All into Practice
So how do you apply this to your daily walk? Start by leaving the pace-obsession behind. For the first few walks, just focus on how you feel. Use the talk test to find the level where you're breathing more heavily but can still chat. This is your baseline moderate effort. You might find this corresponds to a brisk walk on flat ground, or a slower pace up a hill. The goal is to maintain that feeling of effort. As you get fitter, you will naturally have to walk faster or tackle steeper inclines to achieve the same level of perceived exertion. This is a sign of progress. You can also play with intensity by incorporating intervals: walk at your moderate pace for a few minutes, then increase your effort to 'vigorous' (where talking is difficult) for 60 seconds, before returning to your moderate pace. This method is a powerful way to boost your fitness without fixating on a specific speed.
