Start the countdown. Sacramento hosts the USA Track and Field Championships this week, and athletes and fans are on their way into town.

Things kick off Wednesday with shot put at the State Capitol, Sac State will host events through Sunday.

If attendance goals are met, the event will be back in 2017. And that has the Sacramento Kings helping with sales.

President Chris Granger says there's plenty of room for everyone.

"We want to make Sacramento a world class city, and I'm thrilled with the success the Republic has having, the River Cats do a fantastic job, and to the extent that we can add some track and field, and other things along the way, we love it," Granger said. 

About a thousand athletes have registered to compete. Thousands of fans are expected to book local hotel rooms.
