It is a quarter way around the track. Most races start out half way on the turn and you run to midway through the straight away.

Internationally- and Olympic-approved tracks are 400 meters, measured on the inside lane. Rules require one of the straighaways to extend beyond the curve of the track far enough to handle both 100-meter dash and 110-metter hurdles, neither of which races are ever run on curves, unless it is an unapproved track.
The finish line of all races is always at the end of the front straightaway.
Every race over 110 meters requires running curves, but regardless of the race, all competitors run identical distances of both curves and straights, accomplished by using "staggered" starts that compensate for the increasingly greater distance around the track for each successive lane.
The easiest way to visualize stagered starts is with a small book. The bound edge could represent the finish line where all the lanes end. Now if you grip the other edge of all the pages and gently roll them upward, the inner pages (which have a smaller radius to travel) will stick out beyond the pages on the outside -- just like the lanes on a track.
Each person runs 100 meters.
It is about .31 of a mile and on a track it is one time around and then 100 meters.
Around a normal track is approximately 1/4 mile (440 yards, 400 meters). Around a normal track is approximately 1/4 mile (440 yards, 400 meters).
Two and a half laps is 1km, thus .25 of the track is 100m.
100 x 100 = 10,000 meters if area 10,000 square meters
It's 300 meters...
That's only about three quarters of one straightaway

2.5 miles = 2.5 x 1609 meters = 4022.5 meters ~ 10 times the 400 track
500 meters of swimming is only ten laps. In yards it is twice as much which is 20.
