Not in the Derby.
No , auto racing and soccer are the most attended sports world wide.
Actually, there are no official statistics for the global attendance of horse racing. However, there is a very strong case to be made that horse racing is, indeed, the most attended sport in the world. Horse racing is very popular across 6 continents and routinely ranks among the most popular sports in those countries where statistics are compiled. In addition to the many large horse racing venues located in/near the world's major cities there is an uncounted universe of smaller tracks serving towns and villages across the globe. Horse racing gains a particular attendance advantage over other sports due to two major factors. Firstly, the legal gambling aspect attracts many people and the betting activity conveniently takes place within the racing facility. Secondly, unlike most other sports, in most countries horse racing knows no off-season. Wherever you are in the world, winter, spring, summer or fall, a horse race is likely within a reasonable driving distance.
