Milkias Maekele and Victor Langellotti were crowned their respective national road race champions, with Connor Swift and Mattie Dodd taking podium spots in the British race.
Racing Academy rider Maekele powered to the win at the National Road Race Championships in Eritrea.
The young rider, at just 20 years old, took the victory from a stunning solo ride to also take his first win of the season.
Langellotti took his second national title of the week, adding the Monaco National Road Race win to his time trial victory.
Racing as part of the Spanish nationals in Sabinanigo, the win will see Langellotti wear the red and white jersey in races for the next 12 months.
Swift and Dodd both animated the British National Road Race Championships, launching attacks early on in the race and making the break with 60km remaining.
The pair worked well together in the break of five riders, which also included eventual winner Fred Wright (Pinarello Q36.5 Pro Cycling Team), Lewis Askey (NSN Cycling Team), and Elliot Rowe (Team Visma Lease A Bike Development).
It ended with a three up sprint between the World Tour riders, with Swift biting first inside the final kilometre, but settled for third place. A valiant effort from Dodd saw him come home in fifth overall, and take the second under-23 spot behind Rowe. Ben Turner finished in 15th place after a supportive performance.
Embret Svestad-Bardseng finished in eighth place at the Danish national championships, having been in a break for most of the day with eight other riders from Uno-X Mobility.
At the French National Road Race Championships, Dorian Godon and Axel Laurance came home 10th and 11th place, respectively, after a punchy 225.5km race in La Tour-du-Pin.
