Freetown — Jeneba Tarmoh, of Sierra Leone descent but born and raised in San Jose, California in the United State of America by Grace and Victor Tarmoh, has emerged as the world's fastest junior athlete.

Tarmoh, who ran at a time of 11.37 sec for the 100m sailed through the entire International Athletics Association Federation (IAAF) World Junior Track & Field Championships without losing a race.

Last Saturday, the University of Tennessee freshman had five victories in all at the City Stadium. After being undefeated in three races, she struck gold in the 100m dash on Wednesday.

Tarmoh ran the opening leg on the gold-medal-winning United States 4x100-meter relay quartet helping the tandem to its second relay triumph in as many days as she joined forces with teammates Shayla Mahan, Gabrielle Glenn and Tiffany Townsend.

Tarmoh helped the U.S. tandem improve from a 43.76 clocking on Friday to a world-junior- leading 43.66 on Saturday as the Americans claimed their ninth gold medal of the meet.
