Lorenzo Finn crossed the line alone, lifting his bicycle into the thin mountain air to win the Tour de l’Avenir’s final stage in yellow.The victory secured his overall victory in the junior Tour de France (the race name translates to English as the ‘Tour of the Future’), by two minutes and 34 seconds, capping arguably the most successful junior career in recent cycling history.The 19-year-old Italian, who is also half-British through his father, is the first rider since Gianbattista Baronchelli in 1973 to win the baby version of the Tour and the Giro in the same season, having won the world championship in successive years in both the under-18 and under-23 categories.Expected to graduate into Red Bull-BORA-hansgrohe’s WorldTour squad next season, Finn has firmly established himself alongside slightly older contemporaries Paul Seixas and Jarno Widar as stars of cycling’s next generation.This sport’s generation is not linear — nobody picked Jonas Vingegaard as a future star at 20 years old, for example — but the Tour de l’Avenir is a decent predictor of future success, with former winners including Seixas, Isaac del Toro, Tadej Pogačar, and Egan Bernal.Other riders to finish on the podium in recent seasons, such as Giulio Pellizzari (Red Bull-BORA-hansgrohe) and Davide Piganzoli (Visma-Lease a Bike), have emerged as top-level riders over the past two years.With the majority of the Tour de l’Avenir’s peloton set to feature in the U23 world championships next month, many ascending to the WorldTour next season, The Athletic looks at who stood out over the past seven days.
