Frankie Dettori is threatening to leave the Jockeys Association if it fails to support calls to raise racing weight limits.

The Irish authorities altered weights rules last year, after a study by Limerick University last year revealed that jockeys were suffering constant dehydration and inadequate body fat and bone density. Detorri is demanding that English authorities follow suite and ease the tough laws that are compromising jockeys’ health.

Last night John Blake, chief executive of the Jockeys’ Association, was hoping to clear the air. He said that he intends to telephone Detorri to discuss his worries.

New Arab racing outlet for lower-rated horses

The Arab Racing Organisation (ARO) now includes thoroughbreds within its race programme for 2006, which runs from May to October.

Open only to Thoroughbreds and Anglo-Arabs – horses with a minimum of 12.5 per cent Arab blood – the 20 races will be exclusively for amateur riders. The contests are set to be conditions-based in the first year with Anglo-Arabs receiving weight from Thoroughbreds on a regularly monitored basis. Only Thoroughbreds three-years old and upwards who have not run within the last three months will be eligible to take part in the new races and in the same period they must not have been in the care of a licensed trainer.

Asked to assess the likely strength of competition between the two breeds, Racing Post Arab expert Sam Walker said: “The extra 13 per cent of thoroughbred blood within the thoroughbreds should not make them much better than the Anglo-Arabs.”
