George Russell finished fastest in Free Practice 1 for the Barcelona-Catalunya Grand Prix, beating McLaren's Oscar Piastri and Ferrari's Charles Leclerc.
Seven rookie drivers competed in the session, with Russell becoming the first driver to dip below the 1m 18s barrier on the medium Pirelli tyre.
The session was not without issues, as Carlos Sainz's Williams suffered problems in the pit lane, and Luke Browning was forced to sit in the garage for the entire session due to electrical issues.
