Gwen Jorgensen today became the first American triathlete to win gold at an Olympic Games. After a flat tyre at London 2012 led to a 38th-place finish, Gwen had clocked up a record 12 out of 12 wins on the ITU circuit, with the 2014 and 2015 ITU World Championship titles both heading to the 30-year-old’s trophy cabinet. And now the Rio Olympic title is hers.
