Usually there is up to 8 lanes
Typical outdoor tracks are 400 meters (440 yards) on the inside lane. Many indoor tracks are 200 meters (220 yards) around, with some as small as 160 meters (176 yards) when space is severely limited.
A lot
In my opinion, it is not if you are running anything more than a 55m dash. Since there are so many turns, you most likely won't get as good times as on a 400m track.
30m
It depends on how long the track is, but on the normal 400M track, it takes a little more than four laps to make a mile (1609.344M), in lane 1. If you use the line marked 400M in each lane, then you will also run 400M in that lane, but once you go past the common start/finish line, you are going more than 400M per lap. The distance covered will be different depending upon whether the outside lane is the 4th lane (some practice and MS tracks), the 6th lane (some small HS tracks), the 8th lane (most HS, college and international tracks) or the 9th lane (some elite college and Olympic level international tracks).
A standard outdoor track is 400 meters long for one lap.
Just one track, few different events on it.
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.
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.
6 meters is about 20 (19.7) feet.
1,207.01 meters = 0.75 miles.
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.
