A BBC commentator was left shocked by Alex Yee’s dramatic overtake of Hayden Wilde to snatch gold in the men’s triathlon.
The Team GB star looked set to settle for silver after a gruelling race saw the New Zealander out in front ahead of the final stretch.
Yee, 26, had maintained a good position throughout the event but had fallen 15 seconds behind Wilde in the final 2500m.
However, he was able to summon everything he had left in the final stretch to fly past his rival and snatch gold.
BBC commentator Matt Chilton, 61, was left stunned as they said: “What a run from Alex Yee.
“Wilde can’t believe it, he has watched Yee go past him and off into the distance.
“He was kidding us all along.
“He knew what he was doing all along and he has broken Wilde.”
Yee completed the swimming section of the triathlon in 18th place and gained more ground during the 40km cycling section.
He and team-mate Sam Dickinson were 4th and 1st in the race as they started the 10km run.

Dickinson heroically sacrificed his race to help Yee out and could be seen cheering him on as he fell off.
Yee hailed Dickinson after the race and insisted that he would try to return the favour.
He said: “He has been my housemate growing up, through Uni and freshers, so special.
“This guy, we lived together for two to three years, he got me out of bed a few times. I’m so proud of him.
“We’ll share a relay team together. We’ll try make this guy’s dreams come true later on.”
Dickinson added: “What a day, Alex is special.
“Alex won, I didn’t win, stepping off the course, one of the hardest things I’ve ever had to do.
“It’s not about me, helping a mate achieve his dreams is special.”
Team GB also picked up a bronze medal in the women’s triathlon earlier in the day.
Beth Potter was able to come out of a gruelling race that saw many athletes crash and finish in third place.
