Rio Olympics 2016: Mariana Pajon and Connor Fields win BMX gold medals
Colombia's Mariana Pajon successfully defended her Olympic title by winning the women's BMX at Rio 2016 as USA's Connor Fields took men's gold.
World champion Pajon, 24, beat USA's silver medallist Alise Post in front of a crowd packed with delighted Colombian supporters.
Venezuela's Stefany Hernandez won the bronze medal.
Dutchman Jelle van Gorkom won men's silver and Colombian Carlos Ramirez took bronze.
Ramirez needed a photo finish to push American Nick Long down into fourth in a final without any British riders.
Great Britain's former world champion Liam Phillips had to withdraw after suffering concussion in a crash in the quarter-finals, while compatriot Kyle Evans failed to progress past the same stage.
Fields, 23, wrote on his parents' garage wall as a teenager that he would become national and world champion and later added to the message that he would also win an Olympic title.
In 2012, he became the USA Cycling BMX champion and the time trial world champion - and now he has fulfilled his promise by completing the set.
