John Gregorek ignored blistered feet to give Georgetown a distance double today in the 61st IC4A Indoor Championships. He outkicked former nemesis Solomon Chebor in the 3,000 meters and anchored the Hoyas to victory in the distance medley relay.

Leo Williams of Navy boosted his meet record in the high jump to 7 feet 4 1/2 inches as he took one more step toward repeating his 1981 accomplishment of indoor and outdoor sweeps of the Heptagonal, IC4A and NCAA titles.

For defending champion Maryland, however, what was a dismal day outside proved no better indoors. Competing to potential only in the pole vault, the Terrapins wound up third with 43 1/3 points, as Fairleigh Dickinson's foreign legion rolled up 56 to win its first IC4A championship.

Maryland still seemed sure of the silver trophy entering the concluding mile relay, but Darryl Bryant went down with a strained left hamstring on the second leg. That enabled Villanova to place second with 47 points and wrecked the Terrapins' dream of a mile-relay berth in next week's NCAA meet.

One Terrapin could find solace in an NCAA qualifying effort, as senior pole vaulter Dennis Lentz reached a personal best of 16-8 3/4 while finishing second on fewer misses to Mark Strawderman of Rhode Island. Vince Reilly was third at 16-5 and Joe Petrillo fifth at 16-1 as Maryland peaked with 16 points in that event.

Villanova, running without its prize freshman, injured half-miler John Marshall, was further afflicted when Carlton Young finished sixth in the 400 meters. The Wildcats, who have won this meet 17 times since 1957, came to the two-mile relay needing first place to overhaul Fairleigh Dickinson. Worn out from running extra events to compensate for Marshall's absence, the Villanova quartet wound up eighth.

"John Gregorek just won his first race for Villanova," said Jack Pyrah, the Wildcats' assistant coach, after the Hoya senior nipped Chebor and deprived Fairleigh Dickinson of two points.

But the Knights, as it turned out, needed to win only one event, the 55-meter dash, to take the team trophy. In posting four seconds, two thirds and a fifth, Fairleigh Dickinson received only two points from an American, Friday's pentathlon contribution of Randy Smith.

Ephraim Serrette of Trinidad won the sprint, Jama Aden of Somalia was second in the 1,000, Oliver Alves of Guyana was runner-up in the 500, Clyde Edwards of Barbados placed second in the 400, Kenyan Chebor was second in the 3,000, Richard Ouma of Kenya finished third in the 800 and the mixed assemblage wrapped up things with third in the distance medley.

Freshman Kevin King broke up that event for Georgetown with a 2:58.5 three-quarters leg and Gregorek closed it out with a relaxed 4:06.5 mile. Freshman John Pedati opened with 1:54.9 for 800 and Pat McCabe covered the 400 leg in 49.6.

In the 3,000, Gregorek whipped past Chebor with 300 meters to go and went on to win in 8:06.8, atoning slightly for steeplechase losses to Chebor in the IC4A and NCAA meets last year.

"He jumped me at the 300 mark in the ICs and NCs last year and I wanted to get him instead this time," Gregorek said. "When I got up to him, I thought he'd go, but he didn't. My feet were really hot. They blistered badly yesterday. I don't know whether it's old shoes or what, but I've tried everything and they still burn."

Williams did not miss through 7-3, which bettered his meet record of 7-2 3/4 set last year and eliminated the last challenger, Paul Souza of Penn State. Williams made 7-4 1/2 on his final try, leaving the bar shaking.
