With so many contenders and nations caught up in fighting each other and eyeballing the big names, there may be a chance for a rider nobody was considering as a threat for the rainbow jersey to upset the odds and take a remarkable victory. We've taken a look at some outside the box wildcards that could attack early and find success in Montreal.
Tobias Johannessen
An obvious centender, but one that's perhaps overlooked. The Uno-X Mobility rider leads Norway at the race and could be a rider allowed to go in a long-range attacking move.
With a habit of sneaking into the
right breakaway moves, a strong climber who rides with general classification contenders and a versatile arsenal to also hold on with the best on rolling terrain, Johannessen is a dangerous rider to let up the road in Montreal.
Davide Piganzoli
Perhaps Italy's secret weapon, the Visma rider has been in strong form in recent weeks. After two Grand Tours of battling in the general classification groups as Jonas Vingegaard's domestique, he has seemingly come into his own.
He won the Tour of Luxembourg last week and looked in terrific form as he closed down general classification attacks and launched his own long-range raid on the third stage. With Italy boasting a team brimming with potential contenders, an aggressive Piganzoli threat could see him escape in an attack while the rest look at Giulio Ciccone, Lorenzo Finn or Christain Scaroni.
Guillermo Thomas Silva
The Uruguayan rider has been a revelation in 2026 with XDS Astana, taking a stage at the Giro d'Italia and wearing the pink jersey. He also took the GC win at the Arctic Race of Norway in summer.
Despite coming from a lower-ranking nation than the traditional favourites, the favourites should think twice before allowing a Uruguayan jersey too far ahead - the 24-year-old will be deceptively hard to reel in.
Jhonatan Narvaez
Similar to Johannessen, Narvaez should already be considered a real threat. While initially billed to form a dangerous duo with Richard Carapaz, his absence means that the UAE rider will be the sole Ecuadorian rider in the race.
With multiple Grand Tour victories, attributes perfectly suited to the circuit's main climb and a classics pedigree, Narvaez is a rider many can expect to at least impact the race in some way.
Jai Hindley
Many forget that the Australian rider finished on the Giro d'Italia podium this year. Despite a quieter Tour de France, Hindley is a rider well-suited to the Montreal circuit.
He finished 10th place in the 2024 GP de Montreal and has been in the top twenty in the past two World Championships. With a strong Australia selection featuring multiple climbers, Hindley could be their best card to play.
Florian Lipowitz
Making his definitve return to the top level,
Florian Lipowitz has been outside the spotlight since his Tour de France crash that saw him break his collarbone during the time trial. Headlining a Germany selection, could he be deemed a rider not worth initially chasing by the rest?
An in-form Lipowitz would not be an easy rider to contain should he find himself as part of an attacking move, and after two months under the radar, could manage to be allowed some rope to prove just that on Sunday.
Other outsiders to watch
Many riders could make the headlines as part of attacking moves. Afonso Eulalio finished in the top ten at GP de Montreal, Matthias Vacek is a strong powerhouse rider who could use the rolling terrain of the course to hold off the chasers if in a breakaway.
Jan Christen's explosive punch is something to watch out for amongst the early attackers while Felix Gall's Vuelta a Espana climbing legs, and lack of a technical descent make him a rider to watch.
Ahead of one of the most open World Championships in recent years, there's over a dozen riders hoping to upset the lead favourites by Sunday evening and win the rainbow jersey.
