 Bailey later dismissed Costas' comments as "a person who knew nothing about track talking about it with a lot of people listening"; nonetheless, the sportscaster's remarks touched a nerve.The 200 metre time almost always yields a "faster" average speed than a 100-metre race time, since the initial slow speed at the start is spread out over the longer distance.In other words, the second 100 metres is run with a "flying start", without the slow acceleration phase of the first 100 metres and without the greater than 0.10 s reaction time of the start.
