But it is fighting a strong campaign to bring the Games back to Spain in 2012, just 20 years after Barcelona hosted them.
A solid evaluation report from the International Olympic Committee has given the Spanish capital high hopes for the final vote in Singapore, although Paris and London are seen as the front-runners.
Madrid promises an environmentally friendly, car-free Olympics and Paralympics, and it has stressed the compact nature of its bid.
Most venues would be in three main zones, with the Olympic park in the east of the city and further clusters in the centre and the west.
The existing athletics venue would be transformed into a 75,000-capacity Olympic stadium, with the athletes' village just 600m away and the aquatics centre and velodrome nearby.
Real Madrid's Santiago Bernabeu and Atletico Madrid's Vicente Calderon stadium are among the central venues.
Equestrian events, modern pentathlon, archery, mountain biking, triathlon and basketball would be staged in the west.
Outside the city, rowing and canoeing would be 47km away at Aranjuez, sailing in Majorca and football preliminaries in Alicante, Barcelona, Cordoba and Malaga.
