Formula 1 champions including Jenson Button are revving their engines on their way to Wembley to raise awareness of drink-driving in the most spectacular way.

Join the Pack, Johnnie Walker’s global responsible drinking initiative is being held the Green Parking in Wembley Park tomorrow from 1pm – 3.30pm.

A special line up of current and former Formula 1 drivers includes McLaren Honda F1 Drivers Jenson Button and Fernando Alonso and two times Formula 1 World Champion Mika Häkkinen who will be up close driving a range of Formula 1 vehicles, including the Johnnie Walker supercar Caparo T1.

The event is free but on a first come first served basis so fans should get there early.

The Pact initiative has so far secured more than two and a half million commitments from people around the world to never to drink and drive.
