It is all due to the corners(all lanes are used in straight sprint i.e under 100m). The corners on the track are much more narrow as you get closer to the middle. It has been determined that your time is effected(slower) on the inside lane than any other lane. The angles of the corners in lane 2-8 have not shown a drop in time and are therefore able to be used fairly.
approximetly 32 ft.
.270 of a mile.
The inside lane is called lane one.
A little more than 400 meters. To be more precise, the line you run around in a track which has an inside lane of 400 metres, and lane width of 1.27 metres including one lane marking, is 407.980 metres.
It depends on many things, from track size to difference in starting lane and the event. for example in the 800m run the racers can break to lane one after either 100m or after 300m. usually the 100m lead differential between say lane 3 to lane 4 is about 4 meters, lane 5 would be 8, 6 would be 12...etc.
On a standard track, one would run on the inside lane and do four complete laps to run 1600 meters (app one mile). The runners who run in any of the outer lanes get a staggered start (head start) to make up for the distance that one loses because of the wider turns. So, just stay on the inside lane and do four laps.
If you begin in lane one, then lane 2 etc. through lane 8, this is a convenient way to keep track of how many laps you've done.If the width of the lanes is 1.27 m (50 inches), and you run around the track once in each lane you will have run:400 (Lane One) +408.99 (Lane Two) +415.959 (Lane Three)+423.939 (Lane Four) +431.918 (Lane Five) +439.898 (Lane Six) +447.878 (Lane Seven) +455.857 (Lane Eight) =3424.439 (Total Meters Run).Suggestion: switch lanes at a consistant position on a straight section of track.
All tracks are not the same, but most have a 400 meter inside lane. Each successive lane is generally 7 meters longer. So lane 8 would be 7 X 7, or 49 meters longer, or 449 meters.
Each lane is 0.9144 m wide. For one lap of the 200 m track, the distance increase per lane is 0.9144 x 2(pi) = 5.745 m Lane 1 on the start line. Lane 2 at 5.75 m Lane 3 at 11.5 m Lane 4 at 17.25 Lane 5 at 23 m
It took the runner almost one minute to complete one lap of the running track.
400 meters. The track is designed so that no mater what lane you are in, the distance is equal as long as lane 6 starts ahead of 5-1. There are starting markers on the track that will say 400m, 200m, ect. and that is how you know where to start. The starting points are scattered because of the potion of your lane, if you are in lane 1, you will be starting in the back. If you are in lane 8, you will be in front. The only time you are not staggered is if you are on a straight path such as a 100m or 50m.
Basically, the 400 meter dash is one race around the track. Everyone is assigned a lane at the starting line, and after the pistol goes off, they must stay in their lane and run all the way around the track approximetely once.
