Auckland Cup Week at Ellerslie Racecourse begins tomorrow and looks set to be bigger and better then ever. Three days of top tier thoroughbred racing will take place kicking off with the running of the $750,000 Group I New Zealand Derby. Auckland Cup Day will take place on Wednesday and is a gruelling handicap race, run over 3200m. It was first held in 1874. Cup week finishes on March 7 with Diamond Day in support of Ronald McDonald House Charities. Auckland Racing Club is hoping to raise about $80,000 to help the charity build desperately needed additional bedrooms at the Auckland house. Visit ellerslie.co.nz for more information.
