Effort refers to how a run FEELS – whether it feels harder or easier. You can measure effort in many ways: breathing patterns, breathlessness, whether you’re able to carry on conversation, how your body feels, and how sustainable your pace is.

The RPE scale (rate of perceived exertion scale – pictured above) is a simple tool made to help you figure out how each run feels effort-wise.
Easy runs should be done at a 1-3 effort level. You should be able to sustain this pace WHILE holding a conversation without an issue.
Heart rate is another helpful tool when trying to figure out your easy run pace. Your easy runs should be done at approximately 60% – 75% of your maximum heart rate.
You can calculate your max heart rate using a number of strategies
and formulas. There are a few popular formulas used to calculate max heart rate – but it’s important to remember that these formulas do have room for error.
Once you know your max heart rate, you can figure out what 60% of your max heart rate would be & what 75% of your max heart rate would be. Your easy pace should be somewhere within that range, depending upon the day.
We’re going to find the easy heart rate range for a 28 year old runner….
STEP 1. CALCULATE MAX HEART RATE
For the first formula (220 – age = max heart rate) we would get 192 max heart rate. For the second formula (207 – .7 x AGE = max heart rate) we would get 187.4 max heart rate. So let’s average them for about a 190 max heart rate.
STEP 2. CALCULATE EASY RUN HEART RATE
Now we’re going to take 190 and figure out our easy heart rate zone. 60% of 190 would be 114. 75% of 190 would be 143.
So, our easy effort heart rate zone would be between 114-143 for this runner.
There isn’t a specific pace that your easy runs should be done at – rather, there is a range of paces that will fall between that heart rate zone & effort zone on any given day. These two should be used in combination to determine what your easy pace should be each day. Listening to your BODY can be key in figuring out the best easy pace – but it can take practice.
Your easy pace might be impacted by factors including:
These should all be taken into consideration when figuring out what pace feels easy and what pace lands you within your easy heart rate zone on a given day (or somewhat close to it).
