MADRID (AP) -- With European rival Rome out of the race, Madrid expects its 2020 Olympic bid to help revive the country's sluggish economy and reinforce Spain's commitment to fight doping.
Organizers presented their bid application to the media Thursday, two days after Rome dropped out because the Italian government refused to supply financial guarantees.
Madrid, which has a bid budget of $50 million, promised compact and environmentally responsible games. Nearly 80 percent of the infrastructure is already completed.
Bid head Alejandro Blanco says it was "impossible" to do more in the fight against doping after Spain again fell under the spotlight following cyclist Alberto Contador's ban.
Madrid is competing against Istanbul, Tokyo, Doha and Baku, Azerbaijan.
