Most running tracks are precisely the same size, many thanks to your adherence to the IAAF technical Specifications. That means that, as a general rule, you can assume that a trip approximately the track in Lane1 is 400 meters, or about ¼ mile.

But if you’re in ~ the regional track doing a workout, you more than likely shouldn’t it is in in Lane1, so how long are your laps in the external lanes? This table will tell you, or you can use the track lane street calculator further down the page.

Or, if you have actually a particular pace the you’re trying come hit, shot the monitor lane speed calculator. It’ll tell you exactly how long each lap requirements to it is in in order to maintain your speed in her selected lane.

### The Math

Think back to her high school geometry days and also you’ll recall that the one of a one is equal to *2πr* (that’s 2 times approximately 3.14 time the radius that the circle). A monitor is basically simply a one chopped in half with 2 straightaways connecting the halves, so to calculation the total distance, we use *2πr+2s* with *s* being the straightaway length.

Those straightaways, follow to IAAF specifications, space 84.39 meter long and the radius of the inside line that Lane1 is 36.5 meters. Carry out the math and that gets you to… 398.12 meters.

*Wait! no it a 400-meter track?* good catch. That is, yet they add in one extra 0.3 meter to account for the broad of the runner’s body. So, instead of using 36.5 meters together the radius for Lane1, we usage 36.8, and also that gets us precisely to 400 meters.

Each roadway is 1.22 meters wide, for this reason you have the right to take that very same equation and also apply that to any kind of of the lanes’ curve radius to gain your lap distance. A lap roughly Lane4 end up being 23 meters longer than a expedition in Lane1, and also a lap roughly Lane8 end up being virtually 54 meters longer. Again, to check out all the lanes’ distances, check out the table.
