Itzulia Basque Country: Seixas Dominates Opening TT in Del Toro Rivalry

If you spend any time at the local coffee shops near Pearl Street or chatting with the early-morning climbing crews heading up Flagstaff Mountain, you know that Boulder, Colorado, doesn’t just follow professional cycling—it breathes it. There is a specific kind of electricity in the air when a new generational talent emerges, and right now, that energy is focused entirely on the Basque Country. While our local riders are grinding through the thin air of the Rockies, the pro peloton has just witnessed a seismic shift in the opening stage of the 2026 Itzulia Basque Country. The narrative has shifted from the established dominance of the old guard to a visceral, head-to-head clash between the sport’s newest prodigies.

The Youth Movement in Euskadi: Seixas and the New Order

The 65th edition of Itzulia Basque Country kicked off with a statement that will be analyzed in every training camp from the Front Range to the Pyrenees. Paul Seixas, riding for Decathlon CGA CMM, didn’t just win the opening time trial; he obliterated it. In a discipline where experience and calculated pacing usually favor the veterans, Seixas crushed Primož Roglič, signaling that the “next era” isn’t coming—it is already here. For those of us who track the progression of these riders, seeing a name like Seixas set the bar this high in the first stage is a reminder of how rapidly the power dynamics in road racing are evolving.

The rivalry between Seixas and Isaac del Toro (UAE Team Emirates-XRG) has develop into the central axis of this race. While the cycling world has spent years obsessing over the rivalry between Tadej Pogačar and Jonas Vingegaard, their absence from this year’s startlist has created a vacuum. It is a vacuum that Del Toro and Seixas are more than happy to fill. This isn’t just about a single stage win; it is about establishing a hierarchy for the future of the WorldTour. When you combine Seixas’s raw power in the TT with the climbing pedigree of Del Toro and the explosive potential of Juan Ayuso from Lidl-Trek, Itzulia becomes a laboratory for the next decade of cycling.

A Course Built for Chaos

What makes this particular edition of Itzulia so fascinating is the sheer brutality of the route. In previous years, the race has always been known for steep climbs and punchy stages, but the 2026 edition has taken this to a new extreme. There are absolutely no bunch sprint stages this year—a rarity that forces the GC contenders to be aggressive from the first kilometer. This lack of “recovery” days for the sprinters means the race is a relentless series of climbs across Euskadi, favoring the lightweight climbers and the versatile “puncheurs.”

To understand the magnitude of Seixas’s performance, one only needs to look back at the 2025 edition. Last year, the race was a masterclass in dominance by João Almeida, who secured the GC in what he called the biggest win of his career. The 2025 race saw a variety of narratives: Maximilian Schachmann’s fourth stage victory in the opening TT, Caleb Ewan’s final professional victory in Stage 2 before his retirement, and the rollercoaster of Alex Aranburu, who was disqualified and then reinstated as the Stage 3 winner. Then there was the sheer grit of Ben Healy, who produced a legendary 56km solo effort to take Stage 5. For Seixas to enter this environment and immediately dismantle a rider of Roglič’s caliber suggests a level of confidence and physiological peak that is rarely seen in riders of his age.

The Strategic Vacuum: Life After Pogačar and Vingegaard

The absence of Pogačar and Vingegaard changes the psychological profile of the race. Usually, the peloton spends much of the week reacting to the moves of the “Big Two.” Without them, the tactical burden shifts. Riders like Primož Roglič (Red Bull-Bora-Hansgrohe) and Brandon McNulty identify themselves in a position where they must dictate the race rather than respond to it. However, the emergence of the youth movement complicates this. When a rider like Seixas shows this kind of dominance, the veterans can no longer rely on the assumption that the youngsters will crack under the pressure of a multi-day stage race.

The historical weight of Itzulia also looms large. With 48 different winners in its history, and record-holders like Alberto Contador and José Antonio González boasting four victories each, the race resists predictability. The 2026 route, with its relentless elevation, is designed to break riders. For the Boulder community, where we prioritize high-altitude adaptation and power-to-weight ratios, the technical demands of this race are a mirror of our own local challenges. The ability to recover between punchy, anaerobic efforts on steep gradients is the only currency that matters in the Basque Country.

Second-Order Effects on Professional Development

We are seeing a trend where the “apprenticeship” period for young pros is shrinking. In previous eras, a rider would spend years as a domestique before being given leadership duties in a WorldTour stage race. Now, the data-driven approach to training and the sophistication of modern coaching mean that riders like Del Toro and Seixas are arriving at the professional level with the physiological markers of seasoned veterans. This shift is forcing teams to rethink their roster builds, placing more trust in “rising stars” to carry the GC burden.

This evolution in the sport often trickles down to the amateur and enthusiast levels. In our own backyard, we witness more local riders adopting the “pro-style” polarized training blocks and utilizing advanced metabolic testing to mimic the efficiencies seen in the WorldTour. The obsession with marginal gains is no longer exclusive to the team bus; it’s happening in every garage and bike shop across the city.

Navigating the Performance Curve in Boulder

Given my background in analyzing elite athletic performance and the intersection of geography and sport, I know that seeing these global breakthroughs often inspires local riders to push their own limits. Whether you are training for a century or attempting to conquer the steepest grades of the Flatirons, the leap from “fit” to “competitive” requires a specific set of professional supports. If you’re looking to translate the inspiration from Itzulia into your own riding here in Boulder, you shouldn’t guess your way through your training.

To avoid the pitfalls of overtraining or suboptimal equipment, here are the three types of local professionals Consider seek out:

High-Altitude Performance Coaches

Look for coaches who specialize specifically in hypoxic training and altitude adaptation. The ideal professional should be able to provide a periodized plan that accounts for Boulder’s elevation, focusing on the balance between intensity and recovery to avoid the burnout often seen in ambitious amateur climbers.

Clinical Bike Fit Specialists

Avoid the “standard” fit. You need a specialist who uses dynamic 3D motion capture and pressure mapping. Look for practitioners who can optimize your position for both aerodynamic efficiency on the flats and sustainable power production on the steep, punchy gradients characteristic of Basque-style racing.

Endurance Nutritionists

Seek out professionals who specialize in metabolic efficiency and fueling strategies for multi-day efforts. The right nutritionist will help you move beyond simple gels and electrolytes to a comprehensive fueling plan that manages glycogen stores and inflammation during high-volume training blocks.
