The Honourable Usain St. Leo Bolt, OJ, C.D. ( /ˈjuːseɪn/; born 21 August 1986), is a Jamaican sprinter and a five-time World and three-time Olympic gold medalist. He is the world record and Olympic record holder in the 100 metres, the 200 metres and (along with his teammates) the 4×100 metres relay. He is the reigning Olympic champion in these three events, and is one of only seven athletes (along with Valerie Adams, Veronica Campbell-Brown, Jacques Freitag, Yelena Isinbayeva, Jana Pittman, Dani Samuels) to win world championships at the youth, junior, and senior level of an athletic event.

Bolt won a 200 m gold medal at the 2002 World Junior Championships, making him the competition's youngest-ever gold medalist at the time (since surpassed by Jacko Gill). In 2004, at the CARIFTA Games, he became the first junior sprinter to run the 200 m in less than 20 seconds with a time of 19.93 s, breaking the previous world junior record held by Roy Martin by two-tenths of a second. He turned professional in 2004, and although he competed at the 2004 Summer Olympics, he missed most of the next two seasons due to injuries. In 2007, he broke Don Quarrie's 200 m Jamaican record with a run of 19.75 s.

Joseph Mathias Kovacs (born June 28, 1989) is an American track and field athlete who competes in the shot put and has a personal record of 20.85 meters outdoors and 20.14 meters indoors.

Before attending Penn State, he excelled in high school and won PIAA titles in the discus and the shot put during senior season. The winning shot put mark of 64 ft 10.75 in (19.7803 m) is the PIAA class AA State record.

Kovacs was born in Bethlehem, Pennsylvania in 1989. He was raised by parents Joseph (deceased 1997) and Joanna Kovacs. He is a 2007 graduate of Bethlehem Catholic High School in Bethlehem, Pennsylvania. Kovacs attended Penn State University and graduated in 2011, majoring in Energy Business and Finance.
