Alonso Edward

Prior to the 2010 season, Edward decided that he would miss the 2010 World Indoor Championships in Athletics in favour of focusing upon the first IAAF Diamond League, keen to become the first South American to break the 10-second barrier. He began his outdoor season in April, winning the 100 m gold at the Central American Games in Panama, but he suffered a strained hamstring in the 200 m and missed much of the year through the injury.

In the 2009 athletics season, Edward had markedly improved from the previous season: at the Texas Invitational meet in early May, he ran 9.97 seconds to break the 10-second barrier, with the wind assistance just over the legal limit (2.3 m/s). Later that month he broke two national records, running 10.09 seconds in the 100 m and 20.34 seconds in the 200 m at a meet in Hutchinson, Kansas. The following month he proved his ability to win at the senior regional level, taking two gold medals in a sprint double at the 2009 South American Championships in Athletics. He beat the competition in the 200 m by almost half a second, finishing with 20.45 seconds.

Further improvements came in the 200 m in Rethymno in July, as he broke his own national record to win in twenty seconds flat. This time ranked him as fourth fastest in the world coming into the 2009 World Championships in Athletics, with only Usain Bolt, Tyson Gay, and Wallace Spearmon running faster.

He set a South American junior record in the 100 m in 2007 and he attended his first World Junior Championships in 2008, finishing in sixth place. He made significant improvements in the 2009 season, setting national records in the 100 m and 200 m in May, and winning both events at the 2009 South American Championships in Athletics. Prior to the 2009 World Championships he again beat the 200 m national record, becoming the fourth fastest runner of the season. At his first ever World Championships he set a South American record to win the silver medal in the 200 metres final, becoming the youngest ever medallist in that event.

Born in Panama City, Panamá, he is of Jamaican descent on his mother's side. He was initially coached by Cecilio Woodruf in his home country and came to prominence on the youth and junior athletics circuit, winning a 100/200 m double at the South American Youth Championships and the 100 m gold at the 2007 South American Junior Championships. His time of 10.28 seconds, at the junior championships, was a new South American junior record, improving upon his own previous mark. He also attended the 2007 Pan American Junior Championships, but pulled up in the heats. Following in the footsteps of fellow Panamanian athlete Irving Saladino, he moved to train in Brazil but an injury interrupted the start of his season, all but eliminating his chances to qualify for the 2008 Summer Olympics. While recovering, Edward moved to the United States and enrolled with Barton County Community College in Great Bend, Kansas, working under the tutelage of Matt Kane. He made his first appearance at a world competition; the 2008 World Junior Championships in Athletics. A season's best run of 10.91 seconds in the 100 m saw him eliminated in the heats stage.
