NOW in its 124th year, this is the country's top competitive international show jumping event of the year. Today is Rover (guess what the first prize is) Fashion Day at the RDS showgrounds in Ballsbridge, Dublin. Judges will be wandering among the crowds between 11 a.m. and 3.30 p.m. The winner will be chosen from 10 finalists at 4.30 p.m., on the Band Lawn. The Kerrygold Nations Cup takes place tomorrow with the Puissance Challenge going ahead on Saturday. Jumping and judging of ponies and horses in their different categories continues until Sunday.
