Sha'Carri Richardson won't race in the Olympics ... but she has committed to running again in August -- and she says she's now gunning to put on "a show" at the event.
The 21-year-old -- who was left off the Team USA roster this month due to a failed weed test and subsequent suspension -- will compete in the Prefontaine Classic in Oregon on Aug. 20-21.
The event will likely be the first she runs in following the conclusion of her ban -- which formally ends on July 28.
