does anyone know where the measurements are taken on a track? what i mean by that is, is 1 mile 4 laps on lane #1? i usually run at my high school track, but i run on one of the 3 outside lanes (#6-8). i was just wondering what the distance is for, say 4 laps on lane #7? i have tried looking this up and have had no luck. any info would be appreciated! thanks!
