San Diego’s longshot effort to become the United States’ bid city for the 2024 Olympics ended June 13 when the U.S. Olympic Committee announced it had narrowed the field to four cities: Boston, Los Angeles, San Francisco and Washington, D.C.

USOC Chairman Larry Probst thanked both San Diego and Dallas, the two cities eliminated from a finalist pool of six cities.

“We very much appreciate the high-quality proposal from San Diego, a city that truly embraces sport and has a long history of supporting Team USA,” Probst said in a statement.

USOC’s decision came some 16 months after the organization contacted 35 U.S. cities to gauge interest in making a bid on the Games. A local Olympics exploratory committee has been working toward winning a bid and it put together a bid package that included future construction of a domed stadium, an indoor sports arena, a swimming complex and a track and field arena.

The USOC said it’s still mulling whether to make a bid on the 2024 Summer Games, and will wait until the International Olympic Committee releases a 2020 Olympic Agenda report on future strategies later this year before deciding. The USOC said if it does bid, it will select a city probably in early 2015.

The IOC deadline for submitting cities is 2015, and the selection will be made in 2017.

The U.S. hasn’t hosted a Summer Olympic Games since 1996 when it was in Atlanta. Los Angeles hosted the Summer Games in 1932 and 1984.
