1 Mile = 1609.344 Meters

So 8 laps around lane 8 at a track is about 2.5 miles. right?

Where are you running at? At my gym they have a chart on the wall that tells you how many laps for each lane to equal one mile. They might have something similar at where your running. If its an outdoor track at a school, ask the gym department.

To equalize the distances run in each lane the start lines are staggered (offset). The inside lane is 400 meters, to obtain the proper 400 meters for the others look for the starting
line marked in each

It is called WORK-ing out for a reason.

Since the distance around the track in lane one, the inside lane, is 400 meters the distance around the track for the other lanes can be calculated by knowing the lane width and a few other measurements. The formula, L = 2S + 2pi(R + (n-1)w) can be used to calculate the distances around the track for the various lanes. In this formula L equals the lane distance, S equals the length of the straightaway, R is the radius of the turn, n is the lane number and w is the width of the lane.

Since the IAAF has standardized track lane widths at 1.22 meters the above formula calculates the distance around the track in lane 2 as 407.67 meters, lane 3 as 415.33 meters, lane 4 as 423 meters, lane 5 as 430.66 meters, lane 6 as 433.38 meters, lane 7 as 446 meters and lane 8 as 453.66 meters.

I have the same question and hope to get a answer.

Ok, so an olympic track has 8 lanes. I've repeatedly heard that 4 laps = 1 mile. But that surely cannot hold true for ALL the lanes; how can 4 laps around the outer-most lane equal 4 laps around the inner-most lane?

So I'm wondering: in WHICH lane do 4 laps equate to 1 mile?

(I'm trying to get this down for timed-5k sessions.)
