A 3k run is 3 kilometres in length. This is approximately the same as travelling 1.86 miles. The amount of time necessary to complete a three-kilometer run is directly proportional to the runner’s average pace.
Run a distance of three kilometres, and an individual who weighs 150 pounds will burn 211 calories. The total number of calories that a runner burns during a race is slightly affected by factors such as their weight. Instead of concentrating on how far a person runs, the publication Runner’s World suggests paying attention to how long they run for. This is due to the fact that the factors that determine whether or not running is beneficial to one’s health are not the distance covered but rather the amount of time that the heart rate is kept elevated for.
