"The possibility that Barcelona and the Pyrenees host the Winter Games is a great opportunity that we won't let slip away," Trias said. "Nevertheless, after speaking with the heads of the other political parties in the Barcelona town hall, the Spanish government, the Spanish Olympic Committee and the International Olympic Committee, they made me see that the conditions for winning didn't exist in 2022."
Barcelona's decision to wait comes a month after Madrid lost for the third straight time in its attempt to win the right to hold the Summer Olympics.
Trias acknowledged that there was still a lot of work to do to prepare a winning bid.
"I think we still have a long way to go," he said. "Barcelona is a prestigious capital associated with the world of sports, but it's not linked to the perception of being a city of ice and snow. In the years to come we have to explain to the world that we have the Pyrenees and the ski resorts an hour and a half away from our beaches."
Trias said his city government must support more funding for Spain's winter sports federations so that its "skiers and skaters" can compete at the top level.
Barcelona would not be the first warm-weather city to take advantage of nearby mountains to hold the Winter Games. The bid points to the 2006 Turin Olympics and 2010 Vancouver Games as examples. The Pyrenees are 90 miles away, much like in those previous host cities.
Barcelona hosted the 1992 Summer Olympics to huge success for the city, transforming it from a postindustrial town into one of Europe's leading tourist destinations.
Almaty, Kazakhstan, has already officially lodged a bid for the 2022 Games. Other potential contenders include Oslo; Munich; a city in Ukraine; and a joint bid from Poland and Slovakia. The IOC will select the 2022 host city in 2015.
