My favorite race is the 100meter dash
Are you a runner? have you ever witness a 100meter dash race?
Yeah,especially in the Olympics,its a sprint race in track and field competitions. 
 It has been contested at the Summer Olympics since 1896 for men and since 1928 for women.
The race is run In track and field event derived from the sport's typical venue: a stadium with an oval running track enclosing a grass field 
Wow, that is amazing i dint know that about the 100meter dash
It would interest you to know that the  world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while.  omen's world record of 10.49 seconds set by American Florence Griffith-Joyner in 1988 
yeah Usain Bolt  is the fastest man in the world i remember when he set that record on the 100meter dash
Justin Gatlin had beat bolt to it in the 100 meter dash ,hes the reigning 100 m World Champion, after beating rival Usain Bolt at the 2017 IAAF World Athletics
