This week, Si and Dan dive deep into Levi's GranFondo – an event renowned for its stunning Californian scenery but equally infamous for its challenging route. We explore the unique dynamic of this event, which successfully blends a mass participation ride with a fiercely contested, unsupported race, truly taking cycling back to its basics! Is this the ultimate test?

Alongside our main talking point, we've got a packed show covering the latest cycling news, tech, and more! Including a new 24-hour indoor cycling record, Marianne Vos' incredible lifetime contract, concerns over potential US cycling tariffs, Gary Fisher's backing of a new eBike brand, the sleek new Colnago V5RS, and Zwift's adjustable cranks.

Plus, we announce competition winners, launch a new competition for a Redshift Cockpit Bundle, pay tribute to the legendary Barry Hoban, and bring you your favourite segments
