40 laps + another 100 meters

Wouldn't it be 90 meters. 1609 meters equals a mile, so 9 meters extra for each mile, x 10 miles.
It would be 90m, but road courses have to be slightly overdistance. 100m seems about right, plus it's easily marked.
93.44 meters behind the start line and then run 10 laps after reaching the start line.
If you are running it on a 400 meter track:
1 mile = 1609.34 meters x 10 =16093.4 meters/400=40.2335 laps
or 40 laps + 93.4 meters
The end of the last 4 x 100 relay exchange zone is 90 meters from the finish line. Move back 3.4 meters towards the 100 meter start and that will be your starting line.
Mile 1 would be 9.34 meters closer to the finisher
Mile 2 -9 add another 9.34 meters

its 1609.344
if you're gonna be precise....be precise...
The question asked "approximately", so the first answer was the right one.
40 laps on a track is 10 miles.
run in lane 2, 40 laps.

sorry, i should have said (more percisely) to run 40 laps JUST inside lane two (in lane one.) Lane 2 is approx. 408 meters (lane width of 1.25 meters), so if you run to the "outside" of lane one you'd pick up the 94 meters over the 40.

Actually if you rounded to tenths it would be 93.5 as its really 93.472187 meters.
The .472187 = 18.599 inches.
.4 = 15.7481 inches and
.5 = 19.685 inches
So the difference between the rounded .4 or .5 would be approx. 4 inches give or take. Let's be precise.

Where the hell did you get 93.472187 meters from?
Thank you uh_no.
I was trying to be more practical then precise. Most people have enought trouble measuring to the centimeter let alone a mm!
There are very few exact conversions English (imperiale) to metric). 1 inch = 2.54 cm EXACTLY is one of them.
10 x 1609.344 = 16093.44 m
There are 633600 in. in 10 miles ((5280 ft/mile * 12) * 10)
A 400m track is 15748 inches (39.37 in./meter * 400m)
6363600 / 15748 = 40.23368046736093
.23368046736093 * 400m=93.47218694437389
.47218694437389 * 39.37=18.59 inches
40 laps + 93 meters + 18.59 inches = 10 miles on a 400m track
Just go find an old-timey 440y track and do 40 laps.

There quite a few of them still around.

Actually, I was sorta wrong. We know there are exactly 2.54 centimeters in an inch. That means that there are (1/2.54) inches in a centimeter. Meaning that ((1/2.54)*100) inches in a meter. So then you get (633600/((1/2.54)*100)). Which is 40.2336 exactly. Subtract 40 and you get .2336. Multiply that by 400 and you get 93.44 meters. Work shown below:
( 633600 / ( ( 1 / 2.54 ) * 100 * 400 ) - 40 ) * 400 = 93.44
