Kristin Armstrong sealed a remarkable third Olympic time trial gold medal in Rio on the eve of her 43rd birthday.

Armstrong came out of retirement for a second time to defend her title and the veteran American proved she is still the best in the business on Wednesday despite her advancing years.

Armstrong clocked 44 minutes 26.42 seconds over the 29.9 kilometre course, denying Russia's Olga Zabelinskaya by 5.55secs, while Anna van der Breggen of the Netherlands added a bronze medal to the gold she won in the road race on Sunday.
