The Sunday races of the Twingo Cup at Autodrom Most were spiced up by light rain, which persisted throughout the day. Luka Grm started the first race from pole position and held the lead even after the first chicane. However, Grm lost control of his car in the rear section of the circuit and spun out. Unable to recover on his own, Grm required the intervention of the safety car. The safety car was deployed once again during the race, extending the battles for positions until the final laps. In the end, Mihajlo Mladenović emerged as the winner, with a lead of 0.931 seconds over Rok Cerar in second place and Lukas Glazer in third, who crossed the finish line 1.160 seconds behind the winner.
The afternoon race took place on a dry track under sunny weather. Mladenović maintained his lead ahead of Cerar and Glazer. Eventually, Miha Fabijan and Luka Grm separated themselves from the rest of the starting grid and engaged in a fierce battle for victory. Their duel for first place continued until the very end. They entered the second-to-last corner side by side and crossed the finish line in the same time. Fabijan emerged as the winner, but the margin was so close that the timing system displayed a difference of 0.000 seconds between Fabijan and Grm.
