An Americanism from the 1930's referring to the continual routine of competative activity
It was in 1960 in America
The origin of the idiom "against the clock" is believed to come from the world of sports, particularly track and field events. Athletes are often timed with a clock during races and competitions, and the phrase was likely first used to describe a situation where a competitor is racing against time to finish before a specific deadline or time limit. It has since been adopted more generally to refer to any situation where someone is working urgently to complete a task within a specified timeframe.

One mile equals to 1 609.344 meters. Countries that use International System of Units that imported some contests such as a mile race or a quarter mile sprint rounded the mile to 1 600 meters and its quarter to 400 meters. For practical terms you might use the 1 600 m race time as the same as the one mile race time, but for precision you may use the full conversion rate bolded above.
In track and field, a 500-meter race typically refers to a distance that is slightly more than a lap around a standard outdoor track, which is 400 meters in circumference. Therefore, a 500-meter race would be equivalent to running one full lap plus an additional 100 meters. In indoor tracks, which are often 200 meters in circumference, a 500-meter race would involve completing two and a half laps.

The original term 'ahead-start' referred to a participant being allowed to begin a race in front of other competitors as part of a planned advantage. The modern idiom 'headstart' arose as the 'a' in 'ahead-start' became confused as a pronoun, which was subsequently dropped. This is where headstart came from.
