What happened: McLarenF1 posted a short practice update from Monaco, tagging the message with #1000thGP and #MonacoGP. The post signals the start of on-track work in the Principality during the team's milestone Grand Prix weekend.
Why it matters: Monaco practice carries extra weight because qualifying position is historically central on the street circuit. The weekend also extends the buildup around McLaren's special 1,000th Grand Prix livery and commemorative Monaco program.
By the numbers: The 2026 Monaco Grand Prix weekend runs June 5-7. McLaren has billed Monaco as its 1,000th Formula 1 Grand Prix entry, returning to the venue where its F1 story began in 1966.
What to watch: Watch Friday practice times for early grip and traffic clues before qualifying. Saturday's session will set the key competitive picture for Sunday's race.
