Charles Leclerc topped the timesheets during the first practice session for the 2026 Miami Grand Prix on Friday [1].

The session serves as a critical benchmark for teams returning to competition after a break. Early performance indicators suggest a competitive edge for Ferrari, while other top teams face immediate technical hurdles as they prepare for sprint qualifying.

Leclerc led the field at the Miami International Autodrome in Florida, establishing an early advantage for Ferrari [1]. The session provided the first on-track data for the 2026 season's resumption in the U.S. [2]. While Leclerc found immediate pace, the Mercedes drivers encountered trouble early in the session, complicating their initial setup for the weekend [1].

This event marks the return of the Formula 1 circuit after a significant gap in the racing calendar. Reports on the exact duration of the hiatus vary, with some sources citing a five-week break [3] and others noting a four-week gap [4]. Despite the discrepancy, teams used the Friday session to refine aerodynamics, and tire strategies for the upcoming sprint events [2].

Engineers and drivers focused on maximizing grip on the Miami circuit, which is known for its challenging surface and heat. The practice session is the first step in a high-stakes weekend that includes sprint qualifying, and the main Grand Prix race [2].

Teams are now analyzing the telemetry from the first session to address the issues seen by Mercedes and to determine if Leclerc's pace is sustainable. The data gathered on Friday will dictate the setup changes made before the next session begins [1].
