This is the 102nd edition of the Intercollegiate Association of Amateur Athletes of America outdoor track meet and it may be another 102 years before they produce a long jump competition to match the one yesterday at Franklin Field.

For Maryland fans, it was especially delightful. First junior Bob Calhoun leaped 25 feet 11-3/4 inches to erase the oldest IC4A meet record, the 25-9-3/4 effort of Cornell's Meredith Gourdine in 1951.

Then, Dennis Ivory, the junior out of Crossland High who has been concentrating on the triple jump, sailed even farther, 26 feet 1/2 inch, for a personal best and an apparent second straight title.

An official mixup delayed the event and Calhoun had to run a 100-meter quarterfinal, so Maryland Coach Frank Costello considered passing Calhouns last jump. Since Calhoun was behind, however, Costello relented and Calhoun returned to soar 26-3 for the gold medal. Ivory kept the record, however, because of excessive wind on Calhoun's last try.

The peaks and valleys continued for Calhoun, the transfer from Essex County College. He stepped on curb - his left leg in the 100-meter semifinal, failed to qualified in that event and left the Terrapins' favored 400-meter relay unit in jeopardy for today's final.

ing during the 100-meter semifinal and pulled up with a cramp in his left calf. That cost Maryland some points and also jeopardizes its favorite's role in the 400-meter relay, although Calhoun said he would be able to run today.

The one-two jump finish, along with Ian Pyka's successful defense of his shot put title, allowed Maryland to finish the first day of competition with 30 points. Villanova, the chief obstacle to a third straight Maryland team championship, posted only six points but the Wildcats were overpowering in the 1,500 meters, where the qualified four finalists, and the 800 and 400, with three each.

"We can do this and still lose by 20 points," Costello said after the long jump. "But what a job those two guys did."

Both Calhoun and Ivory credited the weather for their out-of-sight jumping - bad weather last week that forced them to lighten their training and perfect conditions yesterday.

"Everything was loose." Calhoun said. "When it's cool, I tighten after each jump. I was a little mad, because the officials weren't ready and I couldn't get my last jump in before the 100. That probably helped, too."

"This is the first good weather we've had in I don't know when," said Ivory, whose previous best jump was 25-6 3/4 in this meet a year ago. "I've had a lot of injuries this year - the triple does that - but I'm coming off two weeks' rest and I felt good. When Bobby first came here, he was talking about both of us going over 26 this year. I wasn't so sure about me."

"We've been rooting for each other," Calhoun said."We don't mind who wins as long as it's one of us."

Pyka won the shot at 60-9 1/4, moving ahead to stay on his fourth attempt after Cornell's Dave Doupe, the 1974 and 1975 champion returning from a broken wrist, had led from the opening toss with 60-4.

"I'm glad I had to come back," said Pyka, a junior from Bayonne, N.J. "I needed the competition. It seems like every meet I've been throwing by myself. That was the closest one I've had all year."

Renaldo (Skeets) Nehemiah, Maryland's freshman sensation, looked like a sure winner in the 100 as be breezed through his semifinal in 10.50 seconds. He also holds a virtual lock on the 110-meter high hurdles, where he scared away so many challengers that no trials were necessary yesterday.

Greg (Fly) Robertson, the defender in both hurdles events, was able to cruise through two rounds of intermediates. Nehemiah and Robertson joined Calhoun and Andre Lancaster on the Terrapins' 400 relay team, which advanced in 41.0, which equaled the fastest time, despite some sloppy baton passes.

Robertson led off and Nehemiah anchored, in 46.4, the Terrapins' 1,600 meter relay team, which won its semifinal in the day's fastest time, 3:08.6.

Qualifying for finals today were Mark Fields, 47.3 in the 400; Dan Lampe and Mike Remus in the pole vault and Brian Melly in the high jump. Lancaster reached today's 200-meter semifinals.

Erik Christenson of Navy was fourth in the shot put with 57-1 1/2. The Mids advanced in both the 400 and 1,600-meter relays. Kevin Byrne of Georgetown won his 1,500-meter semifinal in 3:51.0. Chris Kolm of Catholic qualified in the pole vault.
