It's a sunny Saturday in early May at Kezar Stadium, a great day for a high school track-and-field meet. You might assume it's killing University High track coach Jim Tracy not to run free, as he has done most of his life. But you would be wrong. He remains relentlessly upbeat even though he's stricken with amyotrophic lateral sclerosis (ALS). His optimism has inspired his University High girls' cross-country teams to win state titles - four straight, the last three since his diagnosis and 10 overall; the New York Giants to win a Super Bowl; and a documentary, Running for Jim," directed by KGO television reporter Dan Noyes and Robin Hauser Reynolds. Tracy, now 63, ran track at San Francisco's Riordan High in the 1960s and for the next 44 years never stopped running. He once considered himself a professional runner ... and estimates he's put about 80,000 miles on his body's odometer. Now, all of that has changed. "It's worse every year," Tracy says. "Probably 10 percent (weaker each year). It's a generally weakening pattern, but something more particular might happen that makes you understand how much you've lost." But it has also been inspiring for his track teams, who have come together as a family. "Certainly, his disease has affected our success in positive ways," says Jennie Callan, who helped win a state title in cross-country all four of her years and will run track at Yale next year. "His resilience in these four years has inspired us. Also, he hasn't changed much as a coach. The remarkable thing is he's stayed mentally strong." Or as Tracy puts it, "I continue to make them face reality every day. ... That's my goal, their greater success."
