Guinness is marking 100 years of the Cheltenham Festival by changing its iconic shamrock to a lucky horseshoe for the duration of the festival (15 to 18 March).

Guinness is to Cheltenham what strawberries and cream are to Wimbledon — the Irish beer company having sponsored the festival for the past 19 years.

Last year, nearly quarter of a million pints of the famous beer were imbibed during the four days.

Paul Cornell, Guinness marketing manager, said: “We’re delighted that Guinness has become such an established partner of the Cheltenham Festival and we felt it was fitting to mark the 100-year anniversary with something special.”
