Sir Bradley Wiggins and Emma Pooley won the British time-trial championships in Monmouthshire.
Wiggins triumphed in the men's race in a time of 53 minutes 56 seconds over a 26-mile course around Abergavenny.
Pooley clocked 30 minutes 18 seconds over a 12.2-mile course to win the women's event.
In persistent rain, Wiggins, the London 2012 time-trial gold medallist, denied Thomas and Movistar's Alex Dowsett, who had been chasing a fourth successive title.
Although Team Sky have yet to announce their squad for the Tour de France, which begins in Leeds on 5 July, Wiggins is resigned to not being included.
He said: "This is probably my last British time-trial championship so to win it and perhaps never come back again is a nice way to end it."
Pooley, the 2008 Olympic silver medallist, took her third national title as she finished 39 seconds ahead of Katie Archibald, with Dame Sarah Storey 51 seconds behind in third.
Elinor Barker was fourth, Laura Trott fifth and defending champion Joanna Rowsell sixth.
"It is pretty special to win this," said 31-year-old Pooley, who was riding for VC Norwich.
"I was pleased with the way I rode because I was pretty tired at the end, and that is how you should feel."
