With one week left in the Vuelta a Espana, the race remains highly competitive, with Enric Mas leading by two minutes. The early withdrawal of Tadej Pogacar, who suffered a broken collarbone in a crash during the first week, has left the race open for other riders to challenge for victory. The final week includes a key time trial and two summit finishes—strenuous mountain stages that can significantly change the overall standings. British rider Oscar Onley, currently fifth overall, is one of the riders aiming to challenge Mas. At just 23 years old, Onley is chasing his first Grand Tour podium and trails Mas by 5 minutes and 44 seconds. He has had a strong season, finishing fourth at the 2025 Tour de France and achieving solid results in races such as the Tour Down Under, Tour of Britain, and the World Championships. Onley, who grew up in Kelso, Scotland, was inspired to take up cycling through the time-trial discipline of his local club, the Kelso Wheelers. Although he had the potential to be an elite cross-country runner, he chose cycling instead. He started racing in Europe as a junior and joined the Picnic PostNL development team in 2021 before making his WorldTour debut in 2023. His Grand Tour debut in the 2023 Vuelta a Espana was cut short when he crashed and broke his collarbone on stage two. However, 2024 was a breakout year, with a professional win at the Tour Down Under and a second-place finish at the Tour of Britain. In 2025, Onley continued his strong performances, finishing fifth at the UAE Tour, ninth at Itzulia Basque Country, and third at the Tour de Suisse, where he also won a stage. His performance at the Tour de France further cemented his status as a rising star in professional cycling. Onley joined the Ineos Grenadiers, now known as Netcompany-Ineos, over the winter, but his first season with the team has been affected by a shoulder injury and a disrupted spring campaign due to illness and injury. Despite these setbacks, he has regained his form and is now in a position to secure a podium finish at the Vuelta a Espana. Onley has been one of the most consistent climbers in the race, finishing second on stage nine when Mas attacked. However, he lost time on stage 12 after a crash and further lost 1 minute and 15 seconds on stage 14. He currently leads the best young rider standings by just 30 seconds over Jakob Omrzel. With the final week featuring demanding mountain stages and a time trial, Onley will need to perform at his best to secure a podium finish. He is aiming to recover and regain the strong form he displayed in earlier stages of the race.
