Fans can make an online pledge via Facebook or Guinness’ website to take part in the record attempt, which will be verified by Guinness World Record adjudicators.
It will also include fans at Guinness branded events around the world.
Nick Britton, senior brand manager for Guinness, says the campaign has been launched to capitalise on its Rugby Six Nations tie-up and drive Guinness sales in pubs and bars.
He adds: “The brand is currently driving value into the beer category by outperforming the market by 2% over the last three months, giving outlets a fantastic opportunity to increase footfall and profits.
“St Patrick’s Day falls on the same day as the England v. Ireland Six Nations rugby match so licensees have the potential to drive sales even further by combining these celebrations and offer consumers a fantastic night out.”
Guinness will also send out over 17,000 pieces of branded St Patrick’s Day merchandise to fans as part of the promotion.
