Marlborough heads Martell field

The weights for the Martell Cognac Grand National on Saturday look set to rise by 2lbs following the declaration of top-weight Marlborough to run at Aintree tomorrow.

Nicky Henderson’s 11-year-old, who runs in the colours of Robert Ogden, heads a field of seven for the Martell Cognac Cup Chase, the feature event on the first day of the prestigious meeting.
