That assessment came before the decisive moment. What changed was the behaviour of the man next to him. "Jorgenson was not taking many turns. At first, I thought he was bluffing."
When the balance shifted
The two were at the front when the break was caught, and the race finally split among the favourites. On paper, it was a balance of power: a 19-year-old French prospect alongside the
Team Visma | Lease a Bike leader and one of the peloton’s most established stage racers.
Seixas felt something different. "On the flatter section I took most of the pulls but I did not go full gas."
He was measuring. Not panicking. Not overextending.
Then the road tilted upward. "On the steeper part I accelerated again. I kept my effort going and decided to try the solo raid."
Turning instinct into separation
That was the point of separation.
The initial gap was small. Ten seconds. The type of margin that invites cooperation behind. Instead, the chase faltered. Jorgenson slipped back into the group that had been formed by the acceleration. The hesitation Seixas sensed was not theatre.
What followed was not an impulsive move from a teenager riding on instinct. It was a controlled escalation from a rider who understood both his sensations and the dynamics around him.
He had the legs to commit. He had the awareness to recognise vulnerability. And once he chose to go, he did not half commit.
The gap grew beyond a minute. The race fractured into layers behind him. The solo stopped being a gamble and became a statement.
Seixas had said he would only believe in a long raid on a very great day. In Guilherand-Granges, he found one and used it to drop one of the sport’s biggest names not through brute force alone, but through clarity.
At 19 years old, that might be the most significant part of all.
