document: Alphonce Swai , who ran in the 1984 Olympics for Tanzania , but who later fell prey to alcoholism , continues his comeback bid in Sunday 's America 's Finest City HomeFed Half Marathon . The race is scheduled to begin at 7 a.m. at the Cabrillo Monument atop the Point Loma Peninsula . It will wind its way to the finish line in Balboa Park . Swai began his comeback in late May when he ran the Trib 10K , finishing 16th in 30 minutes 8 seconds . Since then , however , Swai has won two races , the Coronado Half Marathon in July , which he finished in 1:04.50 , and the Goodwill Games 10-kilometer run last month in Seattle . The Goodwill Games victory came despite Swai 's taking a wrong turn and running 150 yards in another direction before getting back on track . Now Swai , 26 , is looking to turn in a 1:02 or 1:03 on Sunday . He insists he 'll need that kind of a time to beat a bevy of Mexican and African runners . The runners Swai fears most include : Carlos Ayala of Mexico City , who finished fourth in this year 's Grandma 's Marathon ; Jose Luis Chuela of Mexico , who was second in this race in 1988 -LRB- 1:03:42 -RRB- ; Sam Sitonik of Kenya , who placed fourth in the 1987 America 's Finest City Half Marathon at 1:06:01 ; and Sammy Rotich , a Kenyan who ran a personal best 1:01:55 in 1987 . The women 's field is led by Kim Jones of Spokane , Wash. . Track & Field News ranked Jones third among women marathoners in 1989 and first among U.S. competitors . Jones , 32 , finished the 1989 New York City Marathon second to Ingrid Kristiansen of Norway with a personal-best time of 2:27.54 . Also in 1989 , Jones won the Twin Cities Marathon , placed second in Houston and third in Boston . She will be challenged by Janine Aiello of Toas , N.M. , who placed second in this year 's San Francisco Marathon ; Lynn DeNinnof of St. Louis , who won a gold medal in the 10 kilometer at the 1990 TAC championships ; and Kathryn Evans of Fort Collins , Colo. , winner of the 1990 Nebraska Half Marathon . The course is considered by runners to be a difficult one -- so difficult , in fact , that most elite runners who train in San Diego stay away from the race . `` It is a challenging course , '' Swai said . `` The runner who is smart and thinks through it will be the one who is going to win . You ca n't just go out and run hard on this course . ''
