From Uruguay to Spain to turn professional
Silva's story began to shift while he was still a junior. At just 17 he left Uruguay for Spain to continue developing his career.
"When I was a second-year junior I left home and went to Spain, where I joined an amateur team," Silva explained
in an interview with Marca. The next season was hampered by covid during which Silva did not get to leave the country, but his feats were not forgoten and Caja's development team offered the Uruguayan a platform to restart his journey to pro level.

It was at Caja Rural that he first showed he could be more than a prospect. There he had the chance to race, take on responsibility, and discover his limits. The subsequent move to XDS Astana opened the WorldTour door, and Silva responded immediately.
His progression is even more striking for the range of terrains where he has managed to excel.
The transition: from the Giro to the Spanish classics
Three victories at the Tour of Hainan - two stages and the overall - already hinted the Uruguayan was ready to step up. But it was at the Giro d’Italia where his name reached a different dimension.
Silva took a stage win and, on top of that, earned the privilege of
wearing the Maglia Rosa. A historic result for a rider just beginning his elite journey and, above all, for Uruguayan cycling.
"The stage win and the Maglia Rosa were indescribable," he said. The emotion had an extra layer with his family in Italy. "I’m still speechless, because it was probably the highest point Uruguay has reached in cycling," he added.
Silva did not stop there. In July he chained two major wins in Spain: the Clásica de Ordizia and the Clásica Castilla y León, conquered in just two days. A show of consistency, resilience, and the ability to compete on very different terrain.
That level has put the Uruguayan among the season’s most productive riders and confirms his ceiling is still far from defined.
Silva can finish in any scenario
Silva’s great strength is his adaptability. He does not seem to need a specific race type to be a protagonist. He can survive in the mountains, attack from range, contest reduced finishes, and use his turn of speed.
That versatility explains much of his 2026 breakthrough and makes his future especially compelling. In a peloton increasingly ruled by riders who can compete across terrains, Silva ticks many boxes top teams seek.
And that also highlights what might have been. The Uruguayan came through Caja Rural and Movistar Team had a chance to sign one of the talents rising in Spanish cycling. In the end it was XDS Astana who backed him, and the return has been immediate.
Silva, however, does not forget the path taken. "All this is something I think I hadn’t even dreamed of," he admits. His story aims to inspire other young Uruguayans who want to follow his steps. Though he leaves a clear message: "If they want to be cyclists, they have to come to Europe."
Bigger target: the Montreal Worlds
The season is far from over. Silva is currently racing the Arctic Race of Norway and will then head to altitude camp before the Canadian WorldTour classics and, above all, the 2026 World Championships in Montreal.
The Uruguayan knows it will be a particularly demanding race. He won’t set a hard target, but he is clear he wants to arrive in top condition.
"It will be a very tough race, but I’ll try to prepare as best I can. I’m not setting a specific objective, but I’ll try to get the most I can," he says.
By now, Silva has achieved far more than he likely imagined when he left Uruguay as a junior. He has won in Asia, conquered Spanish classics, raised his arms at the Giro, and worn pink.
The next chapter of his rise could be written in Montreal. And in the meantime, one fact in the peloton is getting harder to ignore: Guillermo Thomas Silva is no longer a promise. He is the real deal.
