The FIA has released the first draft of the 2018 F1 schedule. No real surprises. It starts in Melbourne & ends at Yas Marina. France returns on 24 June at Le Castellet (a.k.a. Paul Ricard). Monaco is still the same day as the Indianapolis 500. Baku moves up the schedule & Sochi moves back. Shanghai & Singapore get the "provisional" asterisk.
And no conflict with Le Mans.
