If you’re looking beyond the Pogačar–Vingegaard–Evenepoel axis, the hottest overall-GC dark horses heading to Lille on 5 July are Florian Lipowitz, Oscar Onley, Lenny Martínez, Kevin Vauquelin, and Matteo Jorgenson. For long-shot glory in jerseys or stage raids, keep your eyes peeled for Jonathan Milan, Biniam Girmay, Wout Van Aert, Lenny Martínez, Oscar Onley, and Mathieu van der Poel.

What Makes a “Dark Horse” in 2025?
Tour de France dark horses aren’t just long odds—they’re riders hiding in plain sight, hovering beneath the superstar smog, ready to pounce when tactics explode, legs crack, or egos clash. Our definition rests on three criteria:
- Bookmaker cutoff: Anyone priced ≥ 28/1 for yellow, per SpinBetter on 20 June.
- Momentum: Results from the past 14 days—Tour de Suisse, Critérium du Dauphiné—and form spanning winter to late spring.
- Role & route compatibility: Riders free to race their race, supported by a parcours with six high-altitude stages, two time trials, and a sprinter-friendly opening week.
These filters trimmed the fat and unearthed five genuine GC threats—and a flank of rogue jersey raiders capable of detonating the race narrative from the shadows.
The GC Dark-Horse Power Rankings
1. Florian Lipowitz (Red Bull–Bora-Hansgrohe)
Latest odds: 28/1
Meet the buzzword of June. Lipowitz didn’t just podium at the Dauphiné—he hunted, hovered, and hung with the sport’s two grand masters, Pogačar and Vingegaard, all week. His final surge for white was clinical. His composure under pressure? Ice-cold. And with Bora-Hansgrohe shifting their GC ambitions post-Roglič, this German prodigy suddenly inherits leadership status with zero internal friction.

He’s built for France 2025: a pure climber with top-5 TT credentials, thriving at altitude and on extended gradients. The Pyrenees and Mont Ventoux TT offer precisely the terrain to unleash a Lipowitz ambush. And if Pogi and Vingo stare each other into stalemate, don’t be shocked if this Red Bull-backed diesel slips through the cracks and into the top three.
2. Oscar Onley (DSM-firmenich PostNL)
Latest odds: 200/1
Onley isn’t just in form—he’s flashing. His Tour de Suisse queen stage win over João Almeida, launched on a 20-minute wall of pain, was the day he transformed from “interesting prospect” into “GC outsider with bite.”
A Scottish climber with puncheur instincts and rapid recovery, Onley benefits from a DSM squad built to explore chaos. Expect him to peak mid-race—Stages 12 to 14 in the Pyrenees scream “Oscar time.” And with long odds and minimal expectations, his leash is longer than most. One good TT and a few tactical breaks, and 200/1 will look comically mispriced.

3. Lenny Martínez (Bahrain Victorious)
Latest odds: 200/1
Lenny is lightning in a bottle. His Dauphiné stage 8 victory, swiped in a gutsy uphill launch, came at the end of a week where he not only wore the KOM jersey but rode with flair and freedom.
What sets Martínez apart isn’t just pedigree—it’s instinct. He hunts mountains. He lives on altitude. He carries France’s burden like it’s a feather, not an anvil. At just 21, the comparison to a young Thibaut Pinot writes itself, but Lenny is smoother on the bike and—perhaps crucially—less haunted by ghosts.
He’s a GC wildcard and a polka dot contender. If he starts to fade in the third week, expect an immediate pivot toward KOM raids.

4. Kevin Vauquelin (Arkéa–B&B Hotels)
Latest odds: 600/1
Call him a “slow burner” if you like—but Kevin Vauquelin is smouldering at the right time. His cool command of the Suisse lead after back-to-back high-altitude climbs revealed a rider in equilibrium: time-trialling well, climbing smart, and holding form late into the spring.
The route flatters him: medium-mountain raids, low-profile summit finishes, and an opening week with room to hide. He’s not built to shadow Pogačar for 21 stages—but he doesn’t need to. The 2025 route opens small windows to top-ten thieves. Kevin fits the bill—and at 600/1, so do the dreams.

5. Matteo Jorgenson (Visma–Lease a Bike)
Latest odds: 50/1
Consistency. Versatility. Tactical IQ. Jorgenson checks every box but raw explosiveness—and that’s fine. His spring was a clinic in diesel dominance: top-five in nearly every stage race he entered, from Paris–Nice to the Dauphiné.
Visma’s internal puzzle—balancing Vingegaard’s throne defense with Jorgenson’s readiness—might crack open new opportunities. If Vingegaard falters early, don’t be shocked to see the American elevated to co-leadership.
Jorgenson’s Tour debut will be pragmatic, precise, and possibly powerful. He won’t light fireworks—but he could quietly bank a top five while everyone’s watching the firestarters.

The Jersey & Stage-Hunter Outsiders
Dark horses aren’t always aiming for Paris. Some aim for punchy glory, targeted raids, and polka dots worn with pride. Here’s who’s lurking in the shadows—ready to ambush.
🟢 Green Jersey: Points Classification Contenders
Jonathan Milan (Lidl–Trek)
He’s built like a freight train but climbs like a barista on an espresso rush. Milan’s Dauphiné sprint win proved he has the high-speed toolkit and the resistance. With Philipsen and Groenewegen eating each other’s wheels, Milan has clear air to dominate intermediates, especially on crosswind-laced days in northern France.
Biniam Girmay (Intermarché–Wanty)
The defending green-jersey winner now carries expectation—but he’s embracing it. Girmay’s acceleration out of technical corners and on slightly uphill finishes remains unmatched. If the race turns wild—and it will—Bini will be dancing through chaos with a smile and a sprint.
Wout Van Aert (Visma)
Ignore the 1000/1 GC odds. WVA is here for destruction. Week 1’s classics-style sprints suit him perfectly, and if the GC guys mess around, he could find himself in green without even trying. If Van Aert is on form—and early signs suggest he is—betting against him in northern France is betting against physics.

🔴 Polka Dot Jersey: Mountains Classification Hunters
Lenny Martínez
He’s not just a climber—he’s a collector. KOM points find him like magnets. If his GC dream collapses mid-race, expect a ruthless switch to polka-dot warfare. The 2025 route, with 51,550 metres of climbing and HC-heavy Pyrenees, plays straight into his alpine obsession.
Oscar Onley
Explosive. Aggressive. Strategic. If Martínez hunts, Onley ambushes. His Swiss stage-5 climb was an audition for future KOM raids. And with 1-HC climbs littered across week two, his watts-to-weight ratio will terrify breakaway companions.
Kevin Vauquelin
Less flash, more grind. Vauquelin’s strength lies in repeatable, medium-mountain efforts—the sort where polka-dot points are banked, not blasted. Arkéa may rally around him as their jersey man, especially if GC ambitions evaporate early.

Breakaway & Stage Specialists to Watch
Mathieu van der Poel
The cobbled drag into Lille on stage one? That’s MVDP’s playground. Recently back from a wrist fracture, his Dauphiné cameo suggested the fire still burns—and the pedals are turning hot. Don’t rule out an opening-day ambush that steals headlines and yellow.
Matej Mohorič (Bahrain Victorious)
The art of surprise is Mohorič’s profession. He builds race calendars around “that one big attack”—and this Tour’s Rhône valley transitions scream “Mohorič moment.” Watch stage 15. He might already be gone.
Magnus Cort (Uno-X Mobility)
Sprinter? Yes. Breakaway merchant? Also yes. Cort’s triple strike at O Gran Camiño confirmed that he’s once again fine-tuned his chaos sensor. Windy, lumpy, unpredictable stages? He’s licking his lips.

Ranked GC dark-horse table
| Rank | Rider & team | Why the hype now? | Latest GC odds* |
|---|---|---|---|
| 1 | Florian Lipowitz (Red Bull–Bora-Hansgrohe) | Dauphiné podium + white jersey, climbing with Pogačar & Vingegaard all week | 28/1 |
| 2 | Oscar Onley (DSM-firmenich-PostNL) | Won Tour de Suisse queen stage, beating Almeida; phenomenal punch on 20-min climbs | 200/1 |
| 3 | Lenny Martínez (Bahrain Victorious) | Stage-8 Dauphiné win, KOM for a day, France’s new hope at just 21 years old | 200/1 |
| 4 | Kevin Vauquelin (Arkéa-B&B) | Leads Suisse after steady climbing and strong TT—route’s medium-mountain days suit him | 600/1 |
| 5 | Matteo Jorgenson (Visma-Lease a Bike) | Versatile diesel engine, top-five in every stage race he’s finished this season | 50/1 |
GC Shakedown Window
Stages 12–14 feature back-to-back mountain days where alliances crack and domestiques die. If Pogačar and Vingegaard play chess, guys like Lipowitz or Onley could slip through and grab time while no one’s watching. The Mont Ventoux TT that follows is ideal for diesel climbers to seal the damage.
Green Jersey Instability
Philipsen vs Groenewegen is a war. And where there’s war, there’s looters. Milan and Girmay can vacuum up intermediate points during echelons, giving them leads without winning bunch sprints outright. That’s how Sagan did it. That’s how Bini might do it again.
Mountains Jersey Math
With over 50,000m of climbing and 23 categorized ascents, there’s enough real estate to mount a jersey challenge even after a GC failure. If Martínez cracks in week 3? Pivot. If Onley falters early? Hunt. The route rewards flexibility—and dark horses thrive on it.
Stage-Win Shopping List
Stage 1 (Lille): Van der Poel versus the cobbles.
Stage 3 (Flanders-style): Van Aert in beast mode.
Stage 9 (Massif Central): Onley or Martínez raid.
Stage 15 (Rhône valley): Mohorič’s heat-seeking missile.
Stage 19 (Loire Valley): Cort and the wind.
Final Thoughts: One Eye on the Odds, One on the Road
Dark horses win Tours – ask Cadel Evans, ask Geraint Thomas, ask Egan Bernal. They don’t roar. They rustle. They don’t dominate – they endure. And the 2025 edition, with its trapdoor route and punchy profile, is built for exactly that kind of story.
Whether you’re betting, blogging, or watching with a bottle of rosé, know these names: Lipowitz, Onley, Martínez, Vauquelin, Jorgenson. Know their momentums, their numbers, their team roles. Come July 3, cross-check the final start list—and act before the bookies do.
Because if history has taught us anything, it’s this: the Tour doesn’t always go to the fastest or the strongest. Sometimes, it belongs to the one they forgot to mark.
