CASTELLI Cycling Podcast··31 August 2026·42 min

About this episode

We caught up with Paul Magnier at Soudal Quick-Step’s altitude camp in Tignes at the end of July to go behind the scenes of his sprinting, training and the technology helping him find another level. We talk aero testing and wind-tunnel development, the Castelli Sanremo 8S Veloce speed suit, lead-out trains, sprint positioning, gym work and explosive power, as well as the technology being developed to improve rider safety, including airbag systems. At just 22, Paul has already racked up 32 professional victories, including three Giro d’Italia stage wins, the Ciclamino jersey and a WorldTour one-day victory. But he’s not stopping there – his ambition is to reach 100 career wins and, one day, become world champion. We also look back at his breakthrough Giro experience, what it’s like going head-to-head with the fastest sprinters in the world, and how his confidence, instinct and understanding of the sprint have evolved. Because at this level, winning isn’t just about producing more watts. It’s about finding speed everywhere. You don’t want to miss this one. It’s a great conversation about speed, confidence, technology and the relentless pursuit of the perfect sprint. We hope you'll enjoy this one!
