Efficient is the 2007 Melbourne Cup horse racing champion after coming from behind in the last lap to win the richest horse race in the world.

The New Zealand horse finished ahead of Purple Moon which came second and Mahler finished at 3rd spot.

Efficient jockey Michael Rodd said that trainer Graeme Rogerson worked hard for them to win the race.

For trainer Rogerson the win came after 5 years of hard work and he was delighted that at last he has trained a horse to win the Melbourne Cup.

Efficient walked away with the $3 million dollars and the 18 carrot gold cup.
