Brockley's breakout star Olympian Alex Yee has topped his silver from Monday by achieving a remarkable gold medal as Great Britain triumphed in the inaugural triathlon mixed relay.

23-year-old Yee was able to run alone down the finishing straight before celebrating with his jubilant team-mates as they won GB's third triathlon medal of the week.

Born in Lewisham, Yee is the fastest pure runner in the history of triathlon but over the past couple of years he has proved himself capable of living with the best on the swim and bike as well, making him a formidable competitor.

The Brockley triathlete won silver on his Olympic debut on Monday in the individual event, and after standing on the podium to receive his medal, Yee said: “It hasn’t really sunk in quite yet, it doesn’t feel quite real that it’s me yet.

“I still just feel like a normal boy from south east London. I hope I can just serve as inspiration to many people that this is possible.

"I’m not anything special, I just really enjoy sport and I’ve been really lucky that it was me.

“I still feel like I’m a child of the sport, I’m going into every race trying to learn things.

"If I can carry on improving my swim then I can be a bit higher up and be in the race every time and that’s the goal for me, just to become the complete athlete rather than be winning everything, and fame and money.”

Saturday's team event saw Jonny Brownlee finally join the family gold rush in his last Olympic race as he helped Great Britain to victory.

Having been in the shadow of his brother for his entire career, Brownlee now finally has his gold - the third for the Yorkshire siblings in a remarkable family haul.

"The Olympics, I've completed it," said an excited Brownlee to the BBC immediately afterwards.

The 31-year-old said: "It's about time. I keep on trying to get gold medals, Alistair's won two so far, and to go home with one and get towards matching him is super special.

"And it's also the first ever (Olympic) mixed team relay in triathlon so we've made history in that. I feel like I've been a part of a lot of history in my career and that's just another one. It's capped off my Olympic career amazingly."

An excellent opening leg from Learmonth ensured Britain were part of a lead group including the United States, Holland and Germany, and Brownlee then produced the fastest leg of the day to give Britain a nine-second advantage.

Taylor-Brown extended that to 22 seconds, putting her fellow individual silver medallist Yee in an extremely strong position heading into the final leg of a 300 metres swim, 6.8 kilometres bike and 2km run.

But hunting down the 23-year-old was French double world champion Vincent Luis, who produced a scintillating swim and caught Yee going into the second lap of the bike.

Yee managed to catch his wheel, though, and another impeccable transition saw him surge on to the run in first place.

He never looked like being caught, opening up an 11-second lead on the first lap as Luis' efforts caught up with him and American Morgan Pearson moved into silver.

Yee was able to run alone down the finishing straight before celebrating with his jubilant team-mates.

Yee admitted he panicked "a little bit" when he was caught by Luis, saying: "These guys did the perfect race up to that point so for me I just wanted to continue that.

"I knew Luis was coming fast and he'd worked quite hard. I knew at that point that I'd probably be able to get him on the run if I stayed with him on the bike.

"It was a big effort to get on to him at the start of the bike. I guess I played to my strengths and was a little bit cunning in a way but I'm really happy."

Yee has spoken about what an inspiration seeing the Brownlees win medals in 2012 was for his own triathlon journey, but it was revealed afterwards that Luis played a part, too.

The Frenchman said: "Back in 2012, after I did my first Olympics, I got asked by a friend if I had any Olympic gear to give to a young guy starting triathlon and I just learned that it was Alex.

"This guy is the new man and you need to count on him. I would also like to thank Jonny Brownlee for everything he did for triathlon. That was amazing."

Yee said: "I just remember receiving a parcel from France and thinking it was really quite odd at the time. But it was from Vince and he'd sent me some of his Olympic kit.

"I was so young at the time and I remember thinking 'Wow, this is pretty amazing'. Somebody who's inspired me so much. Vince is one of the people I look up to the most in the sport. It was pretty special. He's just a legend."

The gold made it eight triathlon medals across the last three Games for Britain, by some distance the best tally of any nation.

"Success breeds success," added Taylor-Brown. "We're only going up from here."
