    I know it’s FP1 but Alonso in P7 is crazy for an Aston that has been awful this season. Potential points for Aston Martin this weekend?

    It's been a great opportunity for the rookies - busy grandstands, huge media presence - and I don't think any of them have done themselves a disservice.

    They've all done a pretty decent job.

    Chequered flag

    The rookie practice session is done.

    Ferrari's Charles Leclerc ends the hour quickest with a time of 1:18.128 on the soft tyre.

    Championship leader Kimi Antonelli, who needs only a top-nine finish in Mexico to be crowned title winner, is second fastest, 0.659 seconds off Leclerc.

    And well done Frederik Vesti. The Mercedes rookie finishes top of the newbies in third place.

  5. Charles Leclerc is showing the Ferrari has pace in the high altitude of Mexico City, but can that speed continue throughout the whole weekend? The Scuderia topped every practice session in Austin but then faded when it came to qualifying.

  6. Carlos Sainz is startled as the Mercedes of Fred Vesti suddenly appears on the racing lines. "What the hell?!" says the Spaniard over the Williams team radio.

    Colton Herta is in for Finn Valtteri Bottas during first practice over at Cadillac and American has reached an important milestone of 24 laps at the Autodromo Hermanos Rodriguez, which means he finally qualifies for an FIA superlicence.

  7. Top five

    1. Charles Leclerc (Ferrari) - 1:18.128

    2. Kimi Antonelli (Mercedes) +0.659

    3. Frederik Vesti (Mercedes) +0.733

    4. Lewis Hamilton (Ferrari) +0.738

    5. Ayumu Iwasa (Red Bull) +0.985

  8. The virtual safety car is cleared so cars can continue with their various run plans.

    At Racing Bulls, Nikola Tsolov is having trouble with his leg. The Bulgarian is stood up in the cockpit, trying to shake out the aches and pains.

  9. Well done, Audi. British rookie Freddie Slater is getting ready to come back out with 11 minutes left of this session.

  10. Virtual safety car

    The yellow flags are out for Aston Martin's Jak Crawford, who has come to a stop on the Mexican track. The American was told by his pit wall to slow down and stop the car, and now the virtual safety car is deployed.

  11. Freddie Slater will be staying in the garage now, but the teenager does get another chance at an FP1 session next weekend in Brazil, so all is not lost for the Briton.

    George Russell is watching on for this hour as Frederik Vesti climbs into the top three on his low fuel, soft-tyre run. He's seven tenths away from Charles Leclerc, but there's only a small between himself and championship leader Kimi Antonelli.

  12. Lewis Hamilton has reached Turn 13 on his latest hot lap but the Briton can't wrangle in that prancing horse, so he stays third on the timesheets.

    Alpine's Pierre Gasly is doing both sessions today and the frenchman, who banked another point in Austin, is fourth quickest behind Hamilton after his run on the soft compound.

  13. Leonardo Fornaroli is having a tough old session in the McLaren. The 21-year-old Italian is given a list of things his issues could be by the pit wall as he struggles to find the sweet spot in Ladno Norris' car.

    Lewis Hamilton gets a flying lap in on the softs but he can't get close to that top marker by Ferrari team-mate Charles Leclerc. The seven-time world champion is a second off the pace in third spot.

  14. Leclerc fastest on softs

    Charles Leclerc has dusted off the soft tyres to see if he can put his car back to the top of the timesheets. The Monegasque driver has a shot at claiming second in the standings himself, as he's only nine points off. Mercedes' George Russell.

    Soft beats hard so far, as Leclerc goes fastest with a 1:18.128.

    Next up on the red rubber is championship leader Kimi Antonelli, who slots into second, 0.659 seconds away from Leclerc's best marker.

  15. 'We'll see what these teams can do in second practice'

    Marc Priestley

    You've got to take all these lap times with a slight pinch of salt. Nobody has been pushing for outright lap times - but that will change.

    When we get into the second session we'll really see what these teams and drivers can do around here.

  16. Hamilton goes quickest

    Ferrari are not running a rookie in this session, so regular drivers both Lewis Hamilton and Charles are both out on track.

    The seven-time world champion is only a point behind George Russell in the fight for second in the standings, and now he's gone above team-mate Leclerc by 0.060 seconds with a time of 1:19.137 on the hard tyre.

    The stewards are going to investigate Audi leaving a cooling fan on Freddie Slater's car after the session, and now it looks like the teenager's practice running is over.

    If Hamilton had entered F1 earlier, how many more WDCs would he have won?

  18. Iwasa high up

    The highest rookie of the 10 that are out on track in Mexico is Red Bull's Ayumu Iwasa, who was third on the timesheets before Lewis Hamilton clocked a marker a couple of tenths quicker. But fourth is still good for 25-year-old Japanese driver.

    Meanwhile, fellow rookie Freddie Slater is down at the bottom of board, and now the Briton has to come into the pit lane, as he has a cooling fan still attached to his Audi.

  19. 'There is so much unknown'

    Marc Priestley
    Ex-F1 mechanic on Radio 5 Sports Extra in Mexico City

    This is what this session is - and it's going to hamper the drivers not in the car.

    The likes of Verstappen and co, although he'll get up to speed very quickly, but there is so much unknown going into the weekend with these 2026 cars.

    It's a huge learning from everybody.

  20. Nikola Tsolov is only seven points off incoming Haas driver Rafael Camara in the Formula 2 standings, and the 21-year-old Bulgarian has been spoken about as a potential replacement for Liam Lawson at Racing Bulls next season.

    This is Tsolov's first F1 practice session, and he's not doing too badly with a time of 1:20.661, placing him eighth behind Nico Hulkenberg and ahead of McLaren Oscar Piastri.

    Australian Piastri, meanwhile, has just had a moment on his medium tyres.
