Currently ranked number two in the 2017 World Triathlon Series, Gómez took up triathlon at the age of 15 after previously playing football and competing in swimming. But in 2000 at a routine medical test revealed an “abnormal heart valve”, leading to a six-year battle between Gómez and the Spanish sporting authorities regarding his right to compete internationally. He initially won this right in 2003, but he was not selected for the 2004 Summer Olympics and in 2005 the CSD banned him from international and domestic competition until 2006.
In the nine years from 2002 to 2010, Gómez took part in 57 ITU competitions and achieved 54 top ten positions, among which are 23 first place finishes. In 2003 and in 2008, Gómez was ITU Triathlon World Champion (both under-23 and Elite categories respectively in 2003). In 2007 and 2009 he was the Elite European Champion. He finished second in the World Championships in 2007 and was the runner up in 2011 ITU Sprint Distance Triathlon World Championships.
In 2010, Gómez was the number one in the World Championship Series ranking, in 2009 he was number two. At the 2010 ITU Triathlon World Championship final in Budapest, Gómez came second to British triathlete Alistair Brownlee, but despite the loss in the final, he won the Championship overall.
At the London Summer Olympics in 2012, Gómez took the Silver medal in men’s triathlon, 11 seconds behind Gold medalist Alistair Brownlee. Following the Olympic games Gómez won the Hy-Vee Triathlon against a highly competitive field. A month later in his first ever cross triathlon race, he won the 2012 XTERRA World Championship.
In 2013, Gómez continued his success from the previous year, winning the Escape from Alcatraz Triathlon and repeating as the Hy-Vee Triathlon winner. He would then go on to win the 2013 ITU World Triathlon Series, his third such title.
In May 2013, Gómez competed in his first middle distance race by taking gold in Challenge Half Barcelona. In February 2014 he raced and won his second middle distance race, Ironman 70.3 Panama.
In 2014, Gomez won his fourth ITU World Championships, winning four out of the eight possible races as well as placing third at the Grand Final. Gomez also won the 2014 Ironman 70.3 World Championship.
In 2015 Gomez took his third consecutive ITU World Championship, and his fifth title overall, by finishing second at the Triathlon World Series Grand Final in Chicago.
