In cycling, cadence is a measure of rotational speed of the crank, expressed in units of revolutions per minute (r/min or rpm). In other words, it is the pedalling rate at which a cyclist is turning the pedals. Cadence is directly proportional to wheel speed, but is a distinct measurement and changes with gearing.
Simplified diagram of gear inches: As the rear sprocket is halfed in size, the distance traveled by the rear wheel doubles, at half the torque. Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent ( direct-drive ) gearing.

The sprint hurdles distance was 80 m outdoors until 1969 and thereafter 100 m; in indoor pentathlon the distance is 60 m. The flat race was 200 m until 1976 and thereafter 800 m . [ 3 ] In elite-level outdoor competition, the pentathlon was superseded in 1981 by the heptathlon , which has seven events, with both 200 m and 800 m, as well as the ...
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. [1] The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
This is a list of the NCAA outdoor champions in the 120 yard hurdles until 1975, with the metric 110 meter hurdles being contested in Olympic years starting in 1932. Metrication occurred in 1976, so all subsequent championships were at the metric distance. Hand timing was used until 1973, while starting in 1974 fully automatic timing was used ...
A distance medley relay is made up of a 1200-meter leg (three laps on a standard 400 meter track), a 400-meter leg (one lap), an 800-meter leg (two laps), and a 1600-meter leg (four laps) in that order. The total distance run is 4000 meters, or nearly 2.5 miles. Aside from the 400 meter segment, which is a sprint, all legs are a middle distance ...
