400/mile times

53-400m

4.01 mile

-One doesn't need terrific 400m speed to break 4 mins.

1600: 445

400: 53

52-53s. relay spilits

3:56--1500; 4:13 mile convert--I think

400 55.9

1500 3.57.1

This is one of the most depressing threads I have ever had the misfortune to read.

How is it possible that so many people are running 48-50 second 400's and 3:59-4:15 miles?

Were you always fast or did you do special work to develop this type of 400 speed?

400m - 48.8

1500m - 3:39

Mile - 3:57

In HS

1600: 4:40

Now Freshman in college. Haven't run a mile, 400: 54.7 indoors.

55 400

4:31 1600

Senior In HS this Year

47.5 400m; 1:48.9 800m; 3:44.5 1500m

I also heard once that double an 800 is your best potential 1500. It was true for me until my junior year in college (1:52 800m, 3:47 1500m).

what i was basically looking for was minimum quarter speed to run certain times. here's a summary of what people have said

slowest 400 times of people who ran under 5:00 mile

62.7, 61.5, 59, 59

under 4:40 mile/4:20 1500

62.7, 59, 59, 57

under 4:30 mile/ 4:10 1500

62.7, 59, 57, 56

under 4:20 mile /4:00 1500

55.9, 54.6, 54, 54

under 4:15 mile/ 3:56 1500

53, 52.5, 52, 51.8

under 4:10 mile/ 3:51 1500

53, 52.5, 49.68, 49.5

under 4:05 mile/ 3:46 1500

53, 52.5, 49.68, 49.5

under 4:00 mile/ 3:42 1500

49.5, 49.68, 48.8, 47.8

now obviously this data isn't perfect, but it gives a rough idea

55 - HS split

3:49 - soph collge (1:56 - soph indoors)

Hmmm, I didn't realize how consistent the numbers would be once you had a large enough data set. Something to mull over for a while. Good work Mark.

400- 56.2

mile- 4:40.8

Also, when I first ran 4:59, I was at 60 sec. 400

400 - 51.0

Road Mile - 4:23

when I ran my 3:48 1500m i was probably in about 50-51 quarter shape, then i started concentrating on my 800m which I ran 1:48 and had a 400m PR of 48.96.

Miles and Miles, isn't you a marathoner?

51 speed is awfully fast

59.9, 5:09

50.2

3:45.8
