He crossed the finish line in 11th place, 2 minutes and 33 seconds behind
stage winner Isaac del Toro, but retained the overall lead by 42 seconds over Matteo Jorgenson and 49 seconds over Del Toro.
“The objective today was to give everything and use my comfortable advantage to keep the jersey,” Tuckwell said
after the stage. “It was an extremely difficult day and that climb was a real ordeal, so I’m very happy that I managed to keep the jersey.”
The Australian was climbing the Grand Colombier for the first time and relied on pacing himself rather than reacting to attacks from his rivals. “It was the first time I had ever ridden that climb. I didn’t know it at all,” he explained. “But I was able to manage my effort at my own pace from start to finish. I didn’t need to respond to attacks, I could simply ride my own tempo.”
As the climb wore on, Tuckwell admitted he was suffering heavily and feared his overall lead might disappear. A message from a roadside spectator, however, helped him find one final effort.
“I really suffered in the middle of the climb,” he said. “I thought it was going to be very close. Then, with about one and a half kilometres to go, someone at the side of the road told me I still had a one-minute advantage. That was exactly the motivation I needed, especially because I had taken out my earpiece. From that point on, I gave absolutely everything to the finish.”

One final test awaits
With only one stage remaining, Tuckwell remains in possession of the yellow jersey, although the gaps have narrowed considerably after the Grand Colombier showdown.
“We’ll see tomorrow if I can keep the jersey until the end,” he said. “Another completely crazy day awaits us, so I’m going to recover as much as possible and fight to defend it.”
The Australian also stressed that he is still learning during his first professional season and views the final stage as another valuable experience for him to continue developing. “It’s my first season as a professional. I’m still discovering where my limits are and the areas where I need to improve,” Tuckwell said. “Tomorrow will be new territory for me again, with new climbs. I’m looking forward to it.”
