For 800 miles, Dick Mackey and Rick Swenson rarely lost sight of each other. With a few others, they jockeyed for position along the length of Alaska. At the end, they found themselves out in front of everyone else, and proceeded to stage the darnedest finish the race has ever seen.

''By the time the two men reached the streets of Nome, they were virtually running side by side,'' Doug O'Harra wrote. ''One hundred yards out, they were even. By the time they entered the 50-yard chute, Mackey had a slight edge. Both men were running.

''Then Mackey's dogs trotted under the burled arch, the finish line.'' The dogs tangled. ''His sled stopped just short of the finish line. Mackey collapsed.

''Swenson . . . kept going and dragged his sled under the finish line. Though his leaders crossed second, Swenson himself crossed under the arch ahead of Mackey.

''Bedlam erupted.''

The decision about who won the 1978 Iditarod is debated today whenever race fans gather. But the rules and race officials said it was the lead dog's nose, not the musher's behind, that determined the winner. They awarded Mackey the victory by one second.

That incredible finish may have been the highlight of Mackey's career, but it's only part of his history with the Iditarod.

''Dick was a dedicated organizer during Iditarod's early years,'' wrote nominating committee member Tom Busch.

Mackey was one of the first mushers to sign up for the initial race, and in his first five races never finished out of the top 10, all the while performing his organizational duties.

He didn't abandon the race when he stopped running himself, serving as race committee president, race manager, trail manager, banquet emcee and start and finish announcer.

''His voice became the public voice of the Iditarod,'' wrote O'Harra, a member of the Hall of Fame selection committee.
