Wind not certain for Sandown Blowing Wind, who finished third in the Martell Grand National for a second year running last Saturday, is far from certain to run again at Sandown later this season.Connections have the option of saddling Blowing Wind in the Attheraces Gold Cup (formerly the Whitbread) at Sandown on April 27th.A first prize of Stg£72,500 is up for grabs, while Blowing Wind would scoop a Stg£100,000 bonus - on offer to any horse placed at Aintree who then goes on to victory in the final big race of the jumps season - if successful.Peter Deal, who owns Blowing Wind, said today: 'We won`t even think about the Attheraces Gold Cup for another week.'We`d want to give Blowing Wind a week to 10 days rest after the National before considering plans.'Trained by Martin Pipe, Blowing Wind jumped with aplomb in finishing third behind Bindaree and What`s Up Boys in the Aintree marathon.Deal added: 'Sandown is a fantastic course but while Blowing Wind stayed very well at Aintree, Iagree his stamina for Sandown would be in question.'
