At age 25 Renny Quow can be best described as a young veteran, having attended four World Championships and approaching his fifth,. Quow has seen the seen the highs and the lows having represented Trinidad and Tobago for the last twelve years, competing as a junior at the regional Carifta Games and as a senior at the Olympic Games and World Championships.     Born August 25, 1987 in Scarborough, Tobago he attended St Andrews Anglican Primary where he was discovered running by a teacher at the school, Mr. Reid. His talent tough was developed by brothers Wade and Gerard Franklin at Zenith Athletic Club who guided him to his early success in the sport. His first success came at the 2005 Carifta Games in Bacolet, Tobago winning the boys 400m title in 46.61secs. After his victory at Carifta he was selected to his first World Championship team in Helsinki, Finland as part of the men 4x400m where he joined Julieon Raeburn, Ato Modibo and Damian Barry making the World Championship final for the first time. In the final though they were disqualified.
The following year he repeated his success at the Carifta Games following that meet he continued his winning trend at the Central America and Caribbean (CAC) junior track and field championships in Port-of-Spain, Trinidad, taking gold in 46.61secs. His significant success of that year was at the World Junior Championships in Beijing, China winning Gold in the 400m in 45.74secs a national junior record. After a successful career in the junior ranks,  Quow went to South Plains College in Texas under the guidance of Blaine Wiley. During his time at South Plains he won the National Junior Collegiate Athletic Association 400m title. In 2008 he turned professional and changed coaches. His new coach being Wayne Lewis and under his guidance Quow saw a steady progress in his times, dipping under 45 seconds for the first time, 44.89 in Barcelona, Spain. He followed that by winning the Trinidad and Tobago national 400m title in 45.19secs. He saved his best performance though for a place that holds great significance to him Beijing, China at the 2008 Olympic Games, running a then personal best time of 44.82 in the semi finals of the men 400m to advance to the final, becoming the first Trinidad and Tobago athlete to make the 400m final since national record holder Ian Morris in Barcelona 1992.
 In the final though he finished seventh in 45.22secs but the experience he was sure to be happy with, making the Olympic Final in his first attempt at the age of twenty. In 2009 by far his best year as a professional to date, with five sub 45 seconds clocking, among those was his 44.91 to retain his national title and his best to date being his 44.53 in the semi final of the World Championships in Berlin, Germany. In the final he ran 45.02secs for third place, his best individual performance as a senior. Quow is also the only Trinidad and Tobago athlete to medal in 400m at the world championships that only adds to his career, he closed out the year with another third place in the (Golden League) meet in Zurich, Switzerland in 44.77secs.   In 2010 injury slowed much of the progress he would have hoped for, with his best time being 45.10secs. The following year , 2011 was better for Quow with success coming at the Central America and Caribbean Championships in Mayaguez, Puerto Rico winning gold in the 400m, 45.44secs. The World Championships in Deagu, South Korea he ran a season best time of 44.82 in the opening round of the 400m but was unable to replicate that performance in the semi final round where he was eliminated.  2012 he saw the highs and ultimate low as a professional career, the highs being a member of the 4x400m relay team that the World Indoor Championships in Istanbul, Turkey included Jarrin Solomon, eighteen year old Jereem Richards and 2012 double Olympic Bronze medallist Lalonde Gordon, to win Bronze in  3.06:65secs a national indoor record. In 2012 Quow ran best time 1:11:20secs in the 600 yards at the Millrose Games in New York. With the London Olympic Games approaching he was eagerly anticipating competing at the  Games but as time drew closer for the opening round of the men 400m, an injury to his hamstring put an end to his hope of competing in his second Olympic Games. The lowest point though was the lost of his coach Wayne Lewis, who died of cancer.  With 2013 season approaching, Quow went back to his college coach Blaine Wiley in Texas, where he gradually improved his time in both 200m and his pet event the 400m, running 200m season best of 20.75secs and 45.65 at national championships in June, finishing third to Deon Lendore and Jarrin Solomon. Together with Gordon, Solomon and Lendore, Quow will be hoping to gain his fourth ever medal at a World Championships.  A young veteran and no doubt a legend, Quow has and continues to be a true ambassador for his sport and country.
