Thanks for the calculations. This is close to the number I came up with
using the calculator on the link that Piedmont provided (I came up with an
estimate of 55cm).

Hi Runners,
I'm trying to find out where to run on a 400 meter track if I want to run
440 yards.
The abstract measure line on a 400 meter track is 20 cm from the inside
edge. 30 cm if there is a raised curb. This measure line is what is 400
meters long.
Additional distance is added using the familiar 2 * pi * r formula.
Since the ovals are circular, whatever displacement R you add to the
radius around the oval contributes 2 * pi * R to the distance around
the track. If you run 10 cm out, you add about 63 cm to the length
(multiply by 3.14 * 2 = 6.28 then round off).
I seem to remember that running on the inside of lane 2 is about
1/4 mile. Is this correct?
You need about 402.25 meters to make 1/4 mile. So in other words 2.25
meters longer around the track. Divide that by 6.28 and it tells you
how many meters out you should be from the measure line. The answer is
0.358 or about 36 cm.
Factoring in the displacement of the measure line, this means 56 cm
from the inside if there is no curb, 66 if there is a curb.
