The race began in 1973. During its formative period (1973–1978) the Honolulu Marathon doubled in size every year- a rate that has been equaled only once. That growth, like the growth of long-distance running itself, came about not from an interest in competition, but from a quest for personal longevity and an enhanced quality of life. Former Honolulu Mayor Frank Fasi has been inducted in the Honolulu Marathon Hall of Fame after documents proved that he was the true founder of the race 40 years ago.

Now drawing more than 20,000 entries a year, the Honolulu Marathon is one of the biggest in the country. Back in 1973, there wasn’t widespread interest in it. But Mayor Fasi knew about the Boston Marathon, and saw its potential here.

At the forefront of the growth of the Honolulu Marathon was cardiologist Jack Scaff, one of the first physicians to prescribe running as therapy for heart disease. In 1977 Sports Illustrated’s senior writer and Olympic marathoner, Kenny Moore wrote a feature story about the race. That article was soon followed by the book “The Honolulu Marathon,” by journalist Mark Hazard Osmun; the book was a revelatory chronicle of the then-unfolding social craze called the “Running Boom,” as exemplified in the Honolulu event.

Unique to the Honolulu Marathon among American marathons is its popularity among runners from Japan, where there are very few marathons open to all entrants. In recent years, the majority of entrants have been visitors from Japan. The marathon is popular enough that the Honolulu Marathon Association maintains an office in Tokyo to process entries. Japan Air Lines has been the title sponsor of the race since 1985. In 2008, 14,406 of the total 23,231 entries were from Japan, which made up nearly 62.0 percent of the field.
