Ed Ayres has been running competitively for fifty-five consecutive years, and he enjoys it as much now as he did when he joined his high school cross-country team in 1956. Ayres placed third in the first New York Marathon in 1970, and he is the only runner of that race still competing today. Having participated in the early growth of American interest in roadrunning, trail-running, and marathons, he also became one of the pioneers of ultrarunning. He placed third in the US 50 Mile championship in 1976 (in 5:46:52), first in the JFK 50 Mile in 1977, and first in four US national age-division championships at 50K road, 50K trail, and fifty miles. He was the founding editor and publisher of Running Times magazine, now published by Runner’s World parent Rodale Press. He also worked for thirteen years as the editorial director of the Worldwatch Institute. He lives in Green Valley, California.
