ParalympicsGB athletes took three medals as they dominated the triathlon event, adding to the impressive haul collected by British stars across a range of sports on Sunday.
Lauren Steadman led the way with gold in the women's PTS5 event, finishing ahead of team-mate Claire Cashmore who will take a bronze medal home.
Steadman, who won silver in Rio, went one better this time as she finished 41 seconds ahead of next best competitor Grace Norman of the USA.
Cashmore rounded off the podium by finishing almost three minutes behind her compatriot after being slapped with a 60-second penalty.
Meanwhile, in the men's race, George Peasgood swam, cycled and ran his way to a silver medal with a time of 58 minutes and 55 seconds.
For Steadman it was vengeance, after an error in the swimming section five years ago saw her lose out on gold to Norman.
"That's a massive redemption. I was devastated after Rio, I was really destroyed, I didn't go anywhere near my bike, my shoes or my swimsuit for seven months," she said.
"My coach told me: 'You're not done yet and keep going'. I put all my faith in him and he got me there.
"It's been hit and miss over the last four years, some races I've won, some I've narrowly missed out on.
"Before Rio I felt the weight of the world on my shoulders and it really got to me.
"This time I knew the pressure was there but because Rio was a terrible experience, I was determined to just enjoy this regardless of whether I got a medal. When it hurt I thought 'this is what I built for'."
Cashmore, an eight-time medallist in her former sport of swimming, now has her first medal since switching to triathlon.
She has "got some thinking to do" before whether deciding to take part in her sixth Paralympic Games in the hunt for more accolades.
The 33-year-old said: "It's a bronze medal at the Paralympics, I've got to take the highlights from that and be proud. It's my first Games as a triathlete, I did the same in Athens as a swimmer and went up the ranks.
"I don't think my performance would have been like that if certain things hadn't happened in the race. I'm in the best shape of my life and there was a lot more in me today, it just wasn't meant to be.
"I wasn't happy with the penalty, they normally give you a warning and they didn't. It's done now, Grace and Lauren had a fantastic race and that is triathlon."
Meanwhile, Peasgood was in the lead for a long time in his race, but was caught by eventual winner Martin Schulz of Germany.
But he will have another opportunity to take gold home from Tokyo when he hunts for another medal in the cycling time trial on Tuesday.
He said: "Everyone is gunning for the win, there are five or six people that could be on the podium and everyone is pushing for the gold.
"Being here is a massive success after the last couple of months, getting here was all I could ever want and getting a medal is just crazy."
