Charles Leclerc topped first practice at the Monaco Grand Prix as Ferrari produced a one-two, with Lewis Hamilton a clear second, in a session that was punctured by two red flags and a heavy crash for Isack Hadjar.
Leclerc finished 0.226 seconds ahead of Hamilton while Max Verstappen was third, 0.513 seconds off the pace, underlining a sizeable early gap between Ferrari and its rivals in the opening run. Kimi Antonelli outpaced George Russell in the timesheet, another detail teams will pore over before the afternoon return.
Practice at Monaco matters because qualifying is all-important here: track position is famously sticky around the harbour. Teams left the morning with limited clean running, and second practice is due to start at 16:00 BST following a 15:45 BST return to the circuit, giving engineers a narrowed window to assess setups before Saturday.
The session’s rhythm was broken twice by red flags. Red Bull’s Hadjar was involved in the most dramatic incident, crashing into the barriers at the exit of the second Swimming Pool chicane and bringing out one of the stoppages; the team lost valuable track time while marshals cleared debris. Aston Martin’s Fernando Alonso also had a scare, sliding through the harbour-front chicane in a moment that could easily have turned into a high-speed impact.
Alonso has been vocal about a recurring transmission issue his team encountered earlier this year in Miami, warning teams that random downshifts at slow, technical braking zones are especially dangerous at tight street circuits. He argued that a repeat would make the track effectively unraceable at certain points and could easily result in a driver being left looking after a needless hit to the wall, comments that took on sharper meaning after his near-miss in practice.
The interruption and incidents complicate what otherwise looked like a tidy opening for Ferrari. Leclerc’s top time and the margin over Hamilton give the Scuderia a headline advantage on raw pace, but both red flags reduced long runs and race-setup laps across the pit lane, leaving questions about tyre life and fuel simulations unanswered. Verstappen’s gap to the Ferraris is small enough to suggest Red Bull will still be in the fight if they can get uninterrupted running later in the day.
Hadjar’s crash removes laps from Red Bull’s data bank at a venue where every metre is precious and track evolution is swift. Teams will now chase simulation time in the second session to replace what was lost and to prepare for the knockout qualifying that will decide Saturday’s grid.
What comes next is straightforward and consequential: teams return at 16:00 BST for a second practice that must deliver clean, comparable running ahead of qualifying. The essential unresolved question after a disrupted FP1 is whether Ferrari’s early advantage will survive a full, incident-free session and the pressure of qualifying, or whether the gaps will close once teams complete longer runs. That will determine whether Leclerc’s morning top time was an early statement or simply a headline from a morning that never really settled.
