The same way you measure it on the flat - with a distance-measuring wheel that clicks for every X meters. As for where to measure (as in the inside track is shorter than the outside), I'm not sure
100 x 100 = 10,000 meters if area 10,000 square meters
If the track is a quarter mile long, 2 and a 1/2 miles
300 meters
About 0.19 miles.
2.5 miles = 2.5 x 1609 meters = 4022.5 meters ~ 10 times the 400 track
About 400 meters in semi auto mode, 300 meters in full auto.
Two and a half laps is 1km, thus .25 of the track is 100m.
Around a normal track is approximately 1/4 mile (440 yards, 400 meters). Around a normal track is approximately 1/4 mile (440 yards, 400 meters).
The track at Flemington Racecourse is 2312 metres long; the race itself is run over 3200 metres.
I think it must be 300 x 30...
It depends. If you are talking about velodromes, some are 420 meters 333 meters and most indoor ones are 240meters. But if it's a track/trail through nature, it can be pretty much any length.
