The idea is one that gets a boost from swimming trials for the Paris Olympics continuing through this week in Lucas Oil Stadium. That venue has a capacity of 32,000 for the event, representing the biggest venue ever for swimming, and has set world records for attendance.

"For the sport, it’s a magnificent outcome. I think for the popularity of that event in the Games, I think that’s a tremendous outcome," said Gene Sykes, chairman of the USOPC. "It is an adjustment, but frankly I think it’s going to be received very well by athletes and others when they understand the quality of the venues and the quality of the support system for athletes that is planned for LA28."

Swimming was among many other noteworthy changes from what organizers planned when they bid in 2017.

LA28 will look to Oklahoma City to host two sports -- softball, because a permanent venue in California seats 2,000 and is below expected demand; and canoe slalom, because no permanent venue exists in the western U.S. IOC recommendations encourage hosts to use existing venues even if they are not in the host city or region.

Wasserman said LA28 has assured that athletes in those sports will be able to participate in the opening or closing ceremony.

Several other hosts have had events far from the host city, especially in team sports with preliminary rounds. Paris has surfing in Tahiti, sailing in Marseille and basketball and soccer games around the country. Wasserman sees the inclusion of Oklahoma City as a similar step.

"LA is weird that we can do all these things here, but what it would require to do all these things here were things that we have committed from the beginning that we weren’t going to do which was build venues just for the Olympics that had no purpose post the Olympic Games," Wasserman said, "so we’re really taking advantage of all the incredible facilities we have, in California, in Southern California but also in the entire country."

For many of its events, LA28 will look to its wealth of venues -- some of which did not exist when it bid. (LA28 does not use corporate names for the venues but they are included here for clarity).

Gymnastics will be held in the Crypto.com Arena, home of the Lakers and Sparks. Basketball will be held in the Intuit Dome, future home of the Clippers. 

Track and field and Para track and field will remain at L.A. Memorial Coliseum.
"LA28 will host athletics, gymnastics, swimming and basketball at some of the best stadiums in the world, which all exist today and once again, nothing new to build," Wasserman said.

The changes in venues reduce costs of temporary builds and are expected to have an estimated $156M in cost savings or increased revenue opportunities.

The city of L.A. must approve changes to venues that move competitions outside of the city.

LA28 has yet to announce changes that assign venues to new sports organizers have added for their edition of the Games. While L.A. would have a wealth of those for baseball, for instance, T20 cricket remains the biggest question mark as L.A. does not have a venue that can accommodate that. Wasserman said LA28 will assess the schedule and field use before deciding on a temporary venue for the sport.
