Jim Hines: First sprinter to run 100m in under 10 seconds dies

US sprinter Jim Hines, the first man to run the 100m in under 10 seconds, has died at the age of 76.

He broke the record in 1968 when he recorded a hand-timed 9.9 seconds at the US Championships.

Hines then broke his own record shortly after while winning gold at the 1968 Olympics, where an electronic timer in Mexico City recorded him at 9.95.

His record held for nearly 15 years until Calvin Smith ran a time of 9.93 in 1983.

That is the longest length of time an athlete has held the record for the men's 100m since the International Amateur Athletic Foundation began keeping track - 110 years ago.

Hines was born in the state of Arkansas in 1946 but was raised in Oakland, California.

He had an early love of sport, namely baseball, but showed a real talent for sprinting as a teenager. He attended Texas Southern University where he ran for the Tigers track team before competing in national championships and the Olympics.

In addition to winning the 100m at the Mexico Olympics, he was also part of the US 4x100m relay team which won a gold.

He ended his sprinting career shortly after the Olympics and joined the NFL.

He spent three years in the league, playing for the Miami Dolphins and the Kansas City Chiefs.
