From the staggered start, it is 400 meters around. The stagger is calculated by subtracting the extra distance one goes around a wider diameter. For each lane it is double the lane width (which in the Olympics is 1.22m) times pi. for each additional lane.
1220 mm (including line width) - see the IAAF Track and Field Facilities manual, available at www.iaaf.org
On a typical track, which is a training, high school, and a college track there are 8 lanes. However, on an olympic or professional track there are 9 lanes.
It has 9 lanes. What's my prize?
390cm but most running tracks have 8 lanes
Usually, there should be 8 lanes on a running track.
because they didnt like the number 3
The definition of an Olympic size swimming pool is 10 lanes each 2.5 meters wide, however to prevent the outside lanes being disadvantaged by having to compete with the waves bouncing off the sides of the pool only the middle 8 lanes are ever used.
8.1.1.2 Tracks and LanesThe infield straight track should have a minimum of 6 but preferably 8 or morelanes separated and bounded on both sides by white lines 0.05m wide. The lanes shallall be 1.22m ± 0.01m wide including the lane line on the right.The oval track should have a minimum of 4 and a maximum of 6 lanes. Thenominal width of the lanes shall be between 0.90m and 1.10m including the lane lineon the right. All lanes shall be of the same width with a tolerance of ± 0.01m to theselected nominal width.
8 lanes.

An Olympic swimming pool usually has 8 lanes, but sometimes has up to 16.
Assuming that we are dealing with a standard track, where the lanes are 42 in. wide and there is no curb on the inside of lane 1, then the answer is 0.257 miles or 413 meters.
This can vary greatly with the width of the lanes. Often Olympic sized pools are about 50 meters long by 25 yards wide.
