What is the difference between walking, brisk walking, and running?

Our recent article on the advantages of walking over running has brought up the topic of what is the difference between a brisk walk and running?

Below are some insights provided by the CDC on the topic:


Any of the below activities are considered to be activities of moderate intensity: 

• Walking briskly (3 miles per hour or faster, but not race-walking)
• Water aerobics
• Bicycling slower than 10 miles per hour
• Tennis (doubles)
• Ballroom dancing
• General gardening

So walking slower than 3 miles per hour would not be a brisk walk but just a walk. 

Any of the activities below are considered to be activities of vigorous intensity:  

• Race walking, jogging, or running
• Swimming laps
• Tennis (singles)
• Aerobic dancing
• Bicycling 10 miles per hour or faster
• Jumping rope
• Heavy gardening (continuous digging or hoeing)
• Hiking uphill or with a heavy backpack

Another way to measure whether one is walking, brisk walking, or running is to measure one's heart rate: 

One way of monitoring physical activity intensity is to determine whether a person's pulse or heart rate is within the target zone during physical activity.

For moderate-intensity physical activity, a person's target heart rate should be 50 to 70% of his or her maximum heart rate.

This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm). The 50% and 70% levels would be:

50% level: 170 x 0.50 = 85 bpm, and
70% level: 170 x 0.70 = 119 bpm

Thus, moderate-intensity physical activity for a 50-year-old person will require that the heart rate remains between 85 and 119 bpm during physical activity.


For vigorous-intensity physical activity, a person's target heart rate should be 70 to 85% of his or her maximum heart rate. 

To calculate this range, follow the same formula as used above, except change "50 and 70%" to "70 and 85%". For example, for a 35-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 35 years = 185 beats per minute (bpm). The 70% and 85% levels would be:
70% level: 185 x 0.70 = 130 bpm, and
85% level: 185 x 0.85 = 157 bpm

Thus, vigorous-intensity physical activity for a 35-year-old person will require that the heart rate remains between 130 and 157 bpm during physical activity.

In order to take one's heart rate, the CDC advises the following technique: 

Generally, to determine whether you are exercising within the heart rate target zone, you must stop exercising briefly to take your pulse. You can take the pulse at the neck, the wrist, or the chest. We recommend the wrist. You can feel the radial pulse on the artery of the wrist in line with the thumb. Place the tips of the index and middle fingers over the artery and press lightly. Do not use the thumb. Take a full 60-second count of the heartbeats, or take for 30 seconds and multiply by 2. Start the count on a beat, which is counted as "zero." If this number falls between 85 and 119 bpm in the case of the 50-year-old person, he or she is active within the target range for moderate-intensity activity.
