As part of the deal, which runs from 2010-2012, the Mirror will have exclusive association with the event as the official media partner.
The partnership will include both in paper and online reader offers, ticket promotions, competitions and editorial support. The Daily Mirror will have a presence at the Liverpool course through advertising hoardings, as well as having the opportunity to distribute the paper to Aintree race-goers.
The event remains one of the most high-profile and popular in the British sporting calendar - last year 8.5 million BBC viewers watched the race live and the broadcaster dedicated 11 hours of prime-time terrestrial TV exposure, in addition to news items and further features.
Richard Wallace (pictured), Editor of the Daily Mirror, said: "This is an ideal partnership for our readers and is further evidence of the Mirror's commitment and long-term investment in racing."
Lorraine Fraser, Trinity Mirror's Marketing Director UK Nationals, said: "We are proud and excited to announce this partnership and we are looking forward to working closely with Aintree Racecourse and John Smith's. This deal is an exciting development and is the perfect fit for Mirror readers which will in turn build further awareness and engagement of this highly prestigious event."
The 2010 John Smith's Grand National meeting will take place from the 8th to the 10th of April in front of 150,000 spectators and a worldwide television audience spanning more than 140 countries and 600 million people.
Julian Thick, Managing Director at Aintree Racecourse, said: "We are delighted to be working with a partner who proves a perfect fit for the racecourse, the event and our other partners. The John Smith's Grand National is an event that engages the Nation and we're in an even stronger position to celebrate this national treasure through the UK's leading tabloid newspaper."
Mark Given, Brands Director, Heineken UK, who own John Smith's, said: "Like the Grand National and John Smith's, the Daily Mirror is an iconic British brand and the new partnership deal uniquely teams the People's race and the People's pint with the People's paper! We are delighted that the Daily Mirror, a title we have collaborated with very successfully across a number of John Smith's brand initiatives, has been installed as the official media partner of the John Smith's Grand National."
