Neil Fachie and wife Lora claimed cycling golds within just over a quarter of an hour for Team GB at the Tokyo Paralympics.
Neil and pilot Matt Rotherham posted a world-record time of 58.038 seconds – smashing their previous record time – as they beat team-mates James Ball and Lewis Stewart to gold in the B 1,000m time trial.
Lora followed suit shortly afterwards; her and Corrine Hall set their own world record on the way to go retaining the B 3,000 pursuit title.
"There are days that are good in the relationship and there are days like today which we'll never forget," Neil told BBC Breakfast.
"We knew this day would be our big one. Finally, we've managed to both do it together, and to both break the world record as well is beyond our dreams.
"We hoped this would happen, but for it to actually come together is mind-blowing."
