Close. Probably 4.15 sec.
I would run on the grass in trainers and time myself. Then I would run on the track in spikes and time myself. Then I would subtract the track time from the grass time, and that would be roughly your answer.
About the distance if you lie down three idiots end to end. Get a couple of your friends to help measure it out
3 90 degree turns?
I love the responses on here so far. I've really nothing more to add.
If you are asking this question, then you're probably running too hard in practice or on some crappy middle school track. Save your best efforts for a real track.
That one got me, too. But if you start at one corner and end at the same corner, you're making only three turns (think about it).
So if a plane was sitting on top of this giant treadmill and it began moving...

Okay, so the runner is making 3 turns, but the loop must still have 4 turns. Right?
The loop starts on a "straightaway", goes about 60m to the first 90deg turn (left, as are all the turns). That turn is actually more than 90degrees, it is even sharper. Then it goes straight for about 150m to the second 90deg turn. Then it curves gently for about 150m till it hits the original straightaway, makes a 90deg turn, and goes 40m to the starting point. Hopefully that description helps everyone's input.
The typical grass conversion coefficient is 1.15 for tallish grass. Multiple sharp turns factor in as 1.08 to 1.12. Let's say the average (1.10) for this case. The spikes conversion factor is .97. So a 60 second 400 on a track with spikes converts thusly: 60 * 1.15 * 1.10 * (1/.97) = 78.2.

Well, I ran workout of (1:14) (1:19, 1:18) (1:17, 1:17, 1:17) (1:20, 1:21, 1:21, 1:17) (1:16, 1:19, 1:15) (1:13, 1:12) (66) (1:20, 1:17, 1:16) (66,67,68,66,64) with a minute rest, so I don't think so buddy.
The conversion factors are correct.
