Two U.S. Olympic swimmers will showcase a synchronized technical routine in Henderson before performing it in front of the world in London.
Mary Killman and Mariya Koroleva will also offer an exhibition performance on Friday at 3 p.m.
They will also offer a preview of their new routine the following day at 1 p.m. during the U.S. Open Synchronized Swimming National Championships.
Athletes and teams will compete for national titles in the junior and senior divisions in several different categories.
The events are being hosted at the Heritage Park Aquatic Complex at Racetrack Road and Burkholder Boulevard.
Tickets for the performances are $1 to $2 at the door, starting at 8:00 a.m. each day.
These are the final performances for Killman and Koroleva, before they head to the Olympic Games.
They will compete August 5-7 at London's Olympic Park Aquatics Centre.
Killman and Koroleva first teamed up as a duet just before the 2011 Pan American Games, where they won silver medals.
