Dame Sarah Storey made history by becoming Britain's most decorated Paralympian of all-time when she fought off both her competition and the terrible weather to take gold in the C4-5 road race.
It was her 17th time she had tasted success in the Paralympic Games, eclipsing the previous record of 16 by swimmer Mike Kenny.
Storey and fellow Brit Crystal Lane-Wright were involved in a sprint at the very end of the contest, but her rival did not have enough left in her legs to keep up as she pulled away to cross the line first.
The 43-year-old has a lot to thank her colleague for, though, as it was Lane-Wright who look over the lead of the chasing pack when they were both more than a minute behind Kirstin Brachtendorf of Germany and helped reel in the leader.
Once they had, the coast was clear for Storey to ride to gold, with her team-mate even telling her she would not fight her for the win after overtaking Brachtendorf.
"This is your gold medal – you don't have to worry, I won't take it. I won't even attempt to take it away from you," Lane-Wright said she had told her partner.
After the race, Storey told of how the pair had helped each other to the medals they won.
She said: "Crystal was saying, 'Get me up the climb, I need to get the silver medal'. And then I just [went] full gas into the finish.
"We didn't have a conversation about how the race would go before but once we're in that race-winning mood, she was able to tell me that she just needed to get up the climb, and that I was just going to take it on to the finish."
It was a complicated race for all the competitors, with heavy rain and terrible visibility making conditions treacherous in the Japanese capital.
Brachtendorf broke away from the pack early in a desperate attempt to do something different in the bid to stop serial-winner Storey, but ultimately she exerted too much energy too soon as she was later swallowed up by the British pair.
Storey said: "We knew we had to time it right because if you go too hard too early, you're burning all your matches, and I didn't expect any help, you know, I'm defending champion and everybody wants me to take them to the line, as it were, so I knew it was my race to judge.
"Crystal came through on the penultimate climb to make sure we closed that gap, and then it was just down to me to try to get us the gap in the finish, so that last descent, I didn't touch my brakes. I just went for it."
She added she had not felt pressure to surpass Kenny's record for British Paralympians, but it was "the sweetest feeling" to achieve it.
The silver won by Lane-Wright will be her last in Paralympic competition, as she has now announced her retirement.
