What happened: McLaren shared a video winding through the streets of Monaco, captioned "Through the streets of Monaco," tagged with #McLarenF1 and #1000thGP. The post continues a run of milestone-themed content from the team's account, including LEGO-branded tie-ins, as it builds toward marking its 1,000th championship Grand Prix at the principality.

Why it matters: Reaching 1,000 Grands Prix is a rare longevity marker for any Formula 1 constructor, and staging it at Monaco — the sport's most storied street circuit — frames the occasion as McLaren's set-piece celebration of its 1,000th Grand Prix at Monaco. The promotional cadence signals the team intends to lean on its heritage through the Monaco weekend.

What to watch: Watch for McLaren's full milestone activations and any special liveries or helmets tied to the 1,000th-GP celebration over the Monaco race weekend.
