My best 400m time is 1:04, best mile is 5:35. My first marathon, which overall felt pretty easy, was 3:36 GPS time, 3:38 official. This took about 1.5 years total to go from not running to running a 5K in 27:30 to running a 5K in 20 minutes. I had probably about 4 months of breaks due to injury or lack of motivation. Step 1: First, we need to find out how much distance the runner covered when they ran 2 3 of the race. We do this by multiplying 2 3 by the total distance of the race, which is 5 kilometers. This gives us 2 3 × 5 = 10 3 kilometers, or approximately 3.33 kilometers. Step 2/6. Step 2: We know that the runner ran this distance in 21 minutes. Suppose in a marathon race, an athlete covers a distance of 42 km in 125 minutes. His pace will be: Pace = 125/42. Pace = 2.97 minutes per kilometer.

Conversion base : 1 kph = 60 min/km. Most people can expect to walk a mile in 15 to 22 minutes, according to data gathered in a 2019 study spanning five decades. The average walking pace is 2.5 to 4 mph, according to the Centers of Disease Control and Prevention. Factors that affect the speed of your pace include physical fitness levels, the incline and your age. qvJQpw.
