Beloki began the day just three seconds behind overnight leader Noah Hobbs and moved into the yellow jersey after the Stage 1 winner was distanced during the first major climbing test of the race.
Early breakaway caught before Col de Portes selection
Jason Tesson, Kenny Molly, Morne Van Niekerk and Maximilien Juillard formed the early breakaway on the 161.9-kilometre route from Saint-Vulbas to Lagnieu.
Juillard led over the first ascent of the Col de Portes, collecting maximum mountains points on the 14.6-kilometre climb. Unibet Rose Rockets controlled the peloton behind before the original move began to break apart.
Molly and Juillard were caught, while Van Niekerk was also reeled in later. Thomas Gachignard then spent a spell alone at the head of the race before the main contenders took over on the second ascent of the Col de Portes.
EF Education-EasyPost were prominent as Jefferson Alexander Cepeda and Beloki made the front selection. Meehan, Bravo, Mariault, Arsac and Conci were also among the riders to emerge at the head of the race, while pre-stage favourite Wout Poels was left in a chasing group.
Meehan accelerated during the climb before the leading group expanded again, with Arsac and Mariault joining the front. Bouchard, Conci, Buck Jones and Jose Said Cisneros were among those trying to regain contact behind.
Beloki launches winning move
Beloki made the decisive attack with 9.5 kilometres remaining and immediately opened a gap over the rest of the leading group. The Spaniard continued to extend his advantage through the closing kilometres, leaving the chasers unable to bring him back before the finish in Lagnieu.
Isidore emerged as the best of the rest to take second, 54 seconds down, with Conci, Mariault, Arsac, Meehan and Bravo all finishing in the same group. The victory was Beloki’s second at professional level after his Stage 3 success at the 2025 Tour Alsace, where he also went on to win the general classification.
Lev Gonov and Lorrenzo Manzin abandoned during the stage. The Tour de l’Ain concludes with the mountainous third stage from Oyonnax to Lelex Monts-Jura.
