It depends on how fast you're running. A "regular joe" who isn't a runner would probably not be able to run four miles without walking a little bit, and might do 14- to 17-minute miles. An average runner would probably do 10- to 12-minute miles for that distance. A fast runner or a good cross-country runner might do 7- to 9-minute miles. A SUPER fast runner could do 5- or 6-minute miles.
5-minute mile: 20:00
6-minute mile: 24:00
7-minute mile: 28:00
9-minute mile: 36:00
10-minute mile: 40:00
12-minute mile: 48:00
14-minute mile: 56:00
17-minute mile: 1:08:00
Personally, if you're a runner, I think that you should aim to eventually do 4 miles in under 40 minutes. If you're not a runner, just completing 4 miles is great.
About 6.5 km... I do a loop where I live that is about 6.5 km. walking it takes, 59-70 minutes depending who I am walking with. I haven't ran it yet, but pretty sure my height and stride would be give my current condition 33-39 minutes with lots of mid walks to recover. After about a week and cardio improvement, probably down to 23-28 minutes; Thats if I push. I got hte Covid out of shape, so looked around found this Goggins guy and got inspired... looks good for 46.. and I haven't done any runs since about dec 2019. Since i left my gym. I would say, that your height, stride, weight, energy production, waste removed and hydration effect the speed. So attempting to run with all things equal, a taller person should out perform a smaller person. IF all things equal simply be movement and stride distance. All I can really say, is what does it matter you actually got outside and did 4 miles. :D
About 43 minutes.
15 minutes, because 4 miles in an hour is 1/4 hours per mile
at 4mph... after 1 hour, you've run 4 miles. after 2 hours, you've run 8 miles. after 3 hours, you've run 12 miles. I hope you see where this is going.
31 minutes 34.73 seconds.
30 minutes and 3 billion years
time = distance/speed time = 12/4 = 3 hours
It will take 4 hours, provided the runner can maintain that speed.
1 hour. 1/2 hour uphill and another 1/2 downhill.
i think it would take an hour
It would take the team three hours to run 20 miles.
4 hours.
4 hours.
