Renaldo (Skeets) Nehemiah, the world record-holder in the 110-meter hurdles, will test his tender left ankle in the three-day USA/Lite National Track Championships that begin today at Mount San Antonio College in Walnut, Calif.

Nehemiah, a junior at Maryland, has not run since his poor showing in the Pepsi Invitational May 11 at UCLA and he withdraw from his last competition, the International Freedom Games in Philadelphia May 18, after severely spraining his ankle.

Greg Foster, who won the hurdles at the Pepsi meet (Nehemiah finished fourth), will not compete this weekend, opting for some time off after running nine times for UCLA in last weekend's NCAA championships.

But Nehemiah still will have to fend off challenges from Dedy Cooper of the Bay Area Striders; Red Milburn, the 1972 Olympic gold medalist who is coming back from a five-year retirement and Nehemiah's D.C. International teammate, Greg (Fly) Robertson.

"We have not heard from Skeets, but we have his entry," said Hank Ives, publicity director for the meet. As a drawing card, Ives said, "he'll be one of the biggest. He would have been more so if he was running against Foster."

Eight other D.C. International members will join Nehemiah and Robertson at the meet. Chris Persons will run in the 400-meter intermediate hurdles, Cliff Wiley will run in the 100-and 200-meter sprints, John Christian will race in the 100 and Fred Sowerby and Maurice Peoples will compete in the 400.
