Questions
How many laps around a track is a mile?
About 4 laps of a 400 m track: 4.02 in lane 1, because a mile is 1,609 m. The extra 9 m is why mile races start a little behind the usual finish line.
How many laps is a 5K on a track?
12.5 laps in lane 1. A 10K is 25 laps.
Why is lane 2 longer than lane 1?
The bends get wider as you move out. Each lane out adds 7 to 8 m per lap, so lane 8 is about 453 m. That’s why races in lanes use staggered starts. On an easy run, lane 1 or 2 gives you the distance you expect.
How is the lane length worked out?
From the standard track: two 84.39 m straights and two bends with a 36.5 m inner radius, lanes 1.22 m wide. Lane 1 is measured 30 cm out from the kerb and other lanes 20 cm from their inside line, which is how lane 1 comes to exactly 400 m.
Is every track 400 m?
Most outdoor tracks are. Indoor tracks are often 200 m, so double the laps. Some older or school tracks are a different size: check before you count.
