In track geometry, the horizontal layout involves the layout of three main track types: tangent track (straight line), curved track, and track transition curve (also called transition spiral or spiral) which connects between a tangent and a curved track. Curved track can also be categorized into three types.
Delta (200m) – The length a track of this radius is longer than the inside track for a 200m race (and thus how much lead-in is needed to make it a fair race) Delta (400m) – The length a track of this radius is longer than the inside track for a 400m race (and thus how much lead-in is needed to make it a fair race)
The 300 metres is an uncommon (meaning not on an Olympic or World Championship program) sprinting event in track and field competitions. The race starts on a straight and therefore comprises two straights and one bend.
The high school version uses a standard 45 meter start to the first hurdle. Thus the high school race is equivalent to beginning of a standard 400 meter hurdle race, but its placement on the track is shifted 100 meters around the track so it finishes at the common finish line on the straightaway, where the longer race would reach the same point near the end of the second turn.
Middle-distance running events are track races longer than sprints, ranging from 500 metres up to two miles (3218.688 metres). The standard middle distances are the 800 metres , 1500 metres and mile run , although the 3000 metres may also be classified as a middle-distance event. [ 1 ]
A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".
