3 3/4 to 4 laps. it depends
If you were running laps in high school, you were most likely on a regulation size high school court. For this size court, it would have taken you about 19.7 laps to run a mile.
4 laps equal 1 mile
Around a track, 4 laps = one mile. So probably 4.
Four, if it is a regular sized track.
50000 m long & 2055555 laps
Four laps if your school has a 400 meter track (which most high schools do.)
