Zoe Backstedt retained her British national elite women's time trial title, topping an all-Welsh podium at the 2026 championships in Lampeter.
The 21-year-old, who last week won a stage of Tour de Suisse Femmes, covered the 15.9 mile (25.6km) Ceredigion course in 32 minutes and 45 seconds.
World track cycling champion Anna Morris, 31, was runner-up 22 seconds back, with Backstedt's 24-year-old sister Elynor third, 1min 05sec behind the winning time.
Earlier in the day, Ben Wiggins took the Under-23 men's time trial title, with Henry Hobbs second and Finlay Tarling - another Welsh rider on home territory - third.
Wiggins' winning time was 29min 02sec, with Hobbs 1min 19sec slower and Tarling a further three seconds behind.
The elite men's time trial and Under-23 women's time trial races take place later on Thursday.
