This guide explains what the RPE scale is, how to use it, and why it’s a valuable tool for runners of all levels.
If you want to improve as a runner, you need a balanced mix of easy runs and hard workouts in your training.
To execute these effectively, it’s crucial to gauge your intensity accurately.
While pace and heart rate are common methods for measuring effort, factors like weather, terrain, stress, and fatigue can make these metrics unreliable.
That’s where the Rate of Perceived Exertion (RPE) scale comes in, a simple yet effective way to measure effort and keep your training on track.
The Rate of Perceived Exertion (RPE) scale is a subjective 1-10 scale that helps runners measure the intensity of their effort. Unlike pace or heart rate, RPE is based solely on how hard you feel you’re working at any given moment.
It’s adaptable to all conditions—hills, heat, fatigue—and doesn’t require any additional equipment.
RPE measures effort on a scale of 1-10, where 1 is the easiest effort (walking) and 10 is a flat-out sprint.
Most distance training falls between 3 and 8.5 on this scale.
Using the RPE scale effectively requires practice and mindfulness.
Here’s how to get started:
Define what 1 (easy) and 10 (maximal) effort feel like for you. Use these as benchmarks to place your current effort on the scale.
Run a variety of workouts, easy runs, intervals, tempos, fartleks, and pay attention to how they feel at different intensities. Over time, you’ll develop a better sense of what each RPE level feels like.
Effort and feeling aren’t always the same. For example, a hard interval may feel smooth and controlled, but it’s still a high-effort workout. Conversely, an easy run might feel sluggish but should still remain at a low perceived effort.
RPE adapts to factors like heat, hills, and fatigue. For example, an easy pace on a hot day might feel like a 5 RPE instead of a 3. Stick with the effort rather than trying to match your usual pace.
Pace fluctuates on trails due to uneven terrain and elevation changes. RPE lets you maintain the right effort regardless of pace.
In summer, heat and humidity slow you down. Training by RPE helps you avoid overexertion when hitting pace targets isn’t realistic.
During high-mileage weeks, fatigue can make your usual easy pace feel harder. Using RPE ensures you keep easy runs easy, even if they’re slower than normal.
RPE aligns well with the most common training intensities:
Pace/Training Type RPE
The Rate of Perceived Exertion scale is a valuable tool for runners who want to train smarter and adapt to any conditions.
By focusing on effort rather than pace or heart rate, you can ensure your workouts align with your goals while avoiding overtraining.
Whether you’re running trails, training through summer heat, or tackling an intense marathon cycle, the RPE scale is a simple yet powerful way to gauge your intensity and run your best.
