What track lane to use when running a mile?

Answer 1

On a standard track, one would run on the inside lane and do four complete laps to run 1600 meters (app one mile). The runners who run in any of the outer lanes get a staggered start (head start) to make up for the distance that one loses because of the wider turns. So, just stay on the inside lane and do four laps.

Answer 2

If the race is done with a "waterfall" start, then run in lane 1 or as close to it as possible the whole time. If it is more official and there are zones marked by cones on the track specifying where you can cut in, run as close to the inside of the track as you can until you can cut in, then gradually merge toward lane one. lane one is the inner most lane and the shortest distance (400m) around.
