Tobias Foss, Michal Kwiatkowski and Victor Langellotti all claimed National Time Trial Championship victory on a day that saw Netcompany INEOS claim four titles.
The trio all clocked fastest times on Thursday evening, adding to Filippo Ganna's earlier TT success in Italy.
Foss retained his Norwegian skinsuit in Stavanger, setting a time 23 seconds quicker than nearest rival Andreas Leknessund (Uno-X Mobility). The win was Foss' fourth national time trial success, in addition to his world title in 2022.
Embret Svestad-Bardseng was also in action in Norway and claimed fourth place.
Kwiatkowski was another rider who became a four-time champion on the day, taking the win by 1:04 in Raszag. Filip Maciejuk (Movistar) and Piotr Pekala (ATT Investments) rounded out the podium places.
For Langellotti, the day saw him crowned as TT champion of Monaco for the first time.
Racing as part of the Spanish nationals in Sabinanigo, the win will see Langellotti campaigning a striking new skinsuit in time trials for the next 12 months.
Elsewhere the British nationals saw Connor Swift finish runner up to former teammate Ethan Hayter (Soudal Quick-Step) in Wales. The pair were joined by Racing Academy rider Josh Charlton on the podium.
