American cyclist Kristin Armstrong made Olympic history in Rio on Wednesday after coming out of retirement to win the gold medal in the women's individual time trial and becoming the first rider ever to win three gold medals in the same discipline.
Armstrong completed the grueling 29.7-kilometer (18.4-mile) course in 44:26.42 with an average speed of 40.1 kph (24.9 mph).
She beat Russia's Olga Zabelinskaya by nearly five seconds on the rain-soaked course. Road-race gold medalist Anna van der Breggen took bronze.
Armstrong, who turns 43 years old on Thursday, completed a remarkable hat trick, having won gold in the time trial in Beijing and London.
She dedicated her victory to compatriot Mara Abbott, who came up just short of a medal in the women's road race on Sunday, having been caught by a chase group in the final kilometer.
After her first gold in Beijing, Armstrong retired from the sport to become a mother but returned for the London Games to successfully defend her title, NBC noted. Armstrong is the oldest female cycling medalist of all time.
"I don't have words to describe it. When you've already been two times at the pinnacle of the sport, why risk coming back for the gold medal?
"The best answer I can give is that I can," said Armstrong, who retired after each of her two previous Olympic success, only to come back in search of more glory, according to AFP.
"Today the stars aligned. I knew it was going to be a close race. My coach said to me, 'OK, you decide what colour medal you want to have.'
"I dug so deep. I thought about Mara, and I gave everything for her in the final 5km. To hear the national anthem on the podium, that's my favourite part of the Olympics," added Armstrong, who was greeted at the finish with a hug from her 5-year-old son, Lucas.
"Kristen Armstrong is a legend," USA Cycling President Derek Bouchard-Halltweeted. "3 golds in 3 Olympics. LEGEND!"
