Usually the size of a track is determined by the inside measurement, and the track becomes longer in the middle lane, and even longer yet in the outside lane. this is why you see them at most tracks qualify on the inside lane, its shorter.
100 meters. The entire track is 400 meters around.
That depends on the shape of the running track.
If you mean for horse racing, the inside track is shorter then the outside. If you are in a horse race you want to "Hug the rail" and thus save your horse's energy.
If you are looking for good track running shoes, be sure to check the tread based on what surface you are going to be running on. If your idea of track running is on a rubber track then you will want a tread that is shorter. For a shale track you will want something more like a cross trainer in order to get some traction with the running surface.
It would be the same because they line you up further ahead the more outside you get in the starting line to make up for the difference.

The infield.
The area inside a 400-meter running track is approximately 87,120 square feet. This calculation assumes a standard 400-meter track with lane widths of 1.22 meters each.
there is track width (measured from mid rail to mid rail) and track gauge (measured from inside rail to inside rail. As that is the most important size of track, that is normally the distances referenced to. normal distance for track gauge is 1435 mm
Inside is the shortest distance.
Yes! I would normally do the math but I am exhausted. To do the math, you need to know the inside & outside diameter of the track and than convert that figure into its circumference. That gives you an exact answer. In my estimation in will be close to 10% of the overall length which on a 400 meter track would be 40 meters. Using this as a "Guess-timate", running 10 laps in the outer lane will be the same distance as 11 laps on the inside of the track. I ran track to stay in shape for football & wrestling for 4 years and ran on tracks for a great number of years until I became ill.
