Delano Meriwether, the running doctor, refuses to allow time to catch up with him.

A hemotologist with HEW, the 6-foot-2, 165-pounds sprinter who says he is in his "mid-30s," held off a quick field to win the 200-meter open men's final yesterday to highlight the Potomac Valley AAU track and field championships at Maryland's Byrd Stadium.

Meriwether, who won the 100 meters Saturday in 10.2, got an excellent jump out of the blocks and just nipped Barry Crane of Lemans Track Club and Maurice Peoples and Dennis Walker of D.C. International at the tape. Meriwether was clocked in 21 seconds flat.

"I was running for good times. I needed 10.2 and 21.1 to qualify for the AAU Nationals in June," said Meriwether. "There were no slouches in that race either. I ran against good, fast people. I felt I could have done a little better in the 200, but I'm pleased with both races."

When Meriwether who became a notoriety of sorts at meets by running in brightly-colored suspenders, goes against the top amateur sprinters, at the nationals in Los Angeles, he confesses "except for the officials, I'll be the oldest guy there."

Meriwether was asked by coach Fred Sowerby to run a leg on DCI's mile relay, but smiled and declined graciously.

"That's it for me," he said, "I can't today."

Another runner who has forgotten about his age, Ray Adams, picked up two gold medals by winning the 200-and 800-meter events in the Masters 40-49 age division.

The 41-year-old Adams, nipped top rival Larry Colbert in the 200-meter final, but was not pressed in recording a 12-yard win in the 800.

Adams, the defending national champion in the 200, 400 and 800 in his age group, was more elated over his 440 split of 51 seconds on the mile relay.

"My previous best was 51.3," said Adams, "I ran today my best after running the other races. How about that?"

T. C. Williams High School sprinter Tyrone Cross also enjoyed a fine afternoon, winning the junior men's 800-meter dash and running legs on the victorious sprint medley and mile relay teams.

Cross' win in the 800 came as a mild shock, especially since he is primarily a 220 and 440 dash man and he was entered in the 880 against classy middle distance runners Chuck Wimberly of Edison, Mike Stafford of Wakefield and Godfrey Yearwood, the Interhigh 880 champion.
