Bahrain - After the season opener at Melbourne's Albert Park, Bahrain and Shanghai mark the first 'back-to-back' races on the 2018 F1 calendar.

In a preview for Mobil 1 The Grid, Aston Martin Red Bull Racing driver Daniel Ricciardo highlights the challenges of contesting two races in a fortnight, and talks about the unique features of both the Sakhir and Shanghai circuits.

Ricciardo has also given Red Bull a boost by posting the fastest time in the first practice session for the Bahrain Grand Prix on Friday (Apr 6).
