## High School Track Distance Question

### High School Track Distance Question

Hey guys, I've been running on a standard 400m high school track in the
5th lane.  I know 4 laps in lane 1 = mile, so if I'm running 4 laps in
lane 5, what's my distance?  Any math wizards out there with some
help?  Thanks.

Dean,

If you are going by the staggered start bit, make sure it is the staggered
start for the 1 mile instead of just a 440 or something less than a mile.

He stays in lane 5 the whole time. There is no mark for a staggered start
that has one staying in lane 5 for a whole mile, because no races are run
that way. In earlier posts, Oleg mentioned the correct way to measure for
lane 5 (or any other) and gave a good way to approximate.

If you race in the 5th lane then there is no difference because they do a
staggered start to make up for the distance. The track that you run on
should be marked for that kind of start.

### High School Track Distance Question

Let the lane in which you are running be N.
Let the distance in metres around the track when running in lane N be D.

A lap of the track in lane 1 is 400 metres
The length of the straight is the same for all lanes, and is S metres.
The radius of the bend in lane 1 is R metres
The Circumference of a circle is 2 * pi * r.

400 = 2 * S + 2 * pi * R

Each lane is 1 metre wide.
The radius of the bend in lane N is R + ( N - 1) metres.

D = 2 * S + 2 * pi * (R + (N - 1))
D = 2 * S + 2 * pi * R + 2 * pi * (N - 1)
D = 400 + 2 * pi * (N - 1)

When N = 5:
D = 400 + 8 * pi
D ~ 425

Hope this helps,
Nathan.

### High School Track Distance Question

At three feet per lane, you're 12 feet out from Lane 1. Multiply that by
6.28 (two times pi) and you add about 75 feet, or 25 yards, to each lap.

This is not standard and would need to be determined for the track you're
running on, it should be somewhere in the 3-4 ft range.
