Aug 15, 2016 · Short distances make this easy---simply paint a perpendicular line across the track to denote the starting and finishing points. This works quite nicely for the 100 meter race.

If they all started from the same line, then the athletes in the outer lanes would have to run further than the athletes in the inner lanes, because of the semicirclesat the top and bottom of the track. So each lane has to have a special starting position so they all have to run the same distance. Let's learn how to calculate the correct positions ...
How far does each athlete run when they complete one lap of the track?
Let's look first at the route followed by the runner in Lane 1(the inside lane). The rules state that you measure 0.3 m from the inner edge of the lane (about where the runner runs) for Lane 1 if there is a curb. And 0.2 m for all other lanes: From the IAAF Rulebook, Rule 160.2 So this is what it looks like for Lane 1: On the curved sections Lane 1 has a radius of 36.5, but we need to add 0.3 mfor the "running position", for a total of 36.8 m So, how far would you have to run? Answer: the Cir...
Each lane is 1220 wide, so the radius for Lane 2 is 36.5 + 1.22 = 37.72 m And we need to add 0.2 m for the Lane 2 "running position" (remember: 0.3 m for Lane 1, 0.2 m for other lanes), for a total of 37.92 m That is 7.04 m longerthan Lane 1 ... ... so Lane 2 should start 7.04 m after Lane 1to be fair
Can you complete the following table? You should have found that the runner in Lane 8 starts about 53 metersin front of the runner in Lane 1! 1. Does that surprise you? 2. Is it fair? It's fair because, with the staggered start, each athlete runs exactly 400 meters. But some people say that the athletes in the inner lanes have an advantage because ...
You might want to investigate the areaof each lane (imagine you want to paint them different colors). The area is made up of the circular area and the straights. We don't want the athletes running position, we want the radius of the edge. The radius of the inside of Lane 1 is 36.5 m, so the radius of the outside of Lane 1 (which is the same as the ...
Perpendicular Lines. Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope:

Parallel And Perpendicular Lines. Here we will learn about parallel and perpendicular lines including how to show when two lines are parallel or perpendicular, how to calculate the gradient of parallel and perpendicular lines and use this knowledge to calculate the gradient of tangents to circles.
