15 seconds every 100m equals 3:45 for 1500m or 4:01 for a mile. A world record of 9:59 was set by Dennis Edwards on June 1, 1983 at the American Cup in San Diego, California.

The average speed over a mile is approximately 4 minutes per 1000 meters (or 4 miles per hour). To reach the same speed over a mile, you would need to run about 606 meters or 200 feet. This is equivalent to walking at a slow pace for more than 10 minutes.

A standard sprint lasts from 0 to 100 percent of one minute. If your maximum speed is 17 meters per second (60 ft/sec), then you can cover 100 meters in **that minute** in perfect conditions. In reality, you will be able to go only slightly faster than your maximum speed, which is why most sprinters finish **between 90 and 99 percent** of their race length.

The fastest men have covered the half-mile in **under 20 seconds** three times out of four. The best women have done it once in their age group enough times to be ranked among the top eight percent of all female runners worldwide.

Aim for a 2:00 pace, though you'll likely be quicker for shorter rows (50, 100, or 200 meters) and slower for longer ones (500, 1,000, or 2,000 meters). Don't worry about beating a clock; instead, focus on maintaining a steady rhythm. After all, the goal is to feel like you're moving at **a reasonable speed**, not that some guy with a stopwatch is impressed by your efforts.

There are two ways to go about this exercise. You can either use **a heart rate monitor** to stay within a certain percentage of your maximum heart rate or you can time yourself. It's up to you how detailed you want to be with your tracking.

For now, we'll assume you're just trying to keep track of how long it takes you to row 200 meters. That being said, here are three different strategies you can use: count down from 100, count up from 0, or measure out each row for length. The first method is the easiest to record accurately but doesn't give you much information about how you're doing compared to others who may be rowing at different speeds. The second strategy will help you see how your time changes over time while the third allows you to know exactly how long each row lasts.

Start by counting down from 100.

Your 400m average pace is similar to **your 1500m race pace**. If you can average 60.0 for **the 10 x 400m intervals**, you should be able to run the 1500m in 3:45. If you can average 64.0 for the 10 x 400m intervals, you should be able to run the 1500m in 4:00.

So, we would estimate that you should run the 1500m in 3:40 if you are able to average 60.0 for the 10 x 400m intervals.

Now, this is just an estimation. You will need to do some research on how fast other runners have run the 1500m. Also, remember that speed improves over time so if you were to retest yourself after **a few months/years**, you might be able to improve your time even more!

In conclusion, we believe that you should be able to run the 1500m in 3:40 if you can average 60.0 for **the 10 x 400m intervals**.

Seven minutes per mile. If you walk at a rate of 3 miles per hour, it will take you 35 minutes to walk the 5 miles.

The fastest way to travel **some distance** is by running. Theoretically, if you could run forever and never get tired, then you could cover **any distance** in **an infinite number** of steps or strides. In reality, even long-distance runners are limited to about one hour of continuous running without slowing down or stopping to rest.

In terms of kilometers, this means that you can cover 5 km in 7 minutes. Or put another way, you can walk at a rate of 5 kms per hour.

Of course, you can't keep walking forever, so the next question is how long does it take to walk 10 km? The answer is approximately 45 minutes. So, if you want to walk very far, you'll need to figure out how many miles you can walk in an hour.

60 miles per hour is considered fast for **a car driver**, but not for someone who is walking.
