Olympians Dr. Duncan Macdonald (Honolulu), Trish Porter (Albuquerque, N.M.), Val Barnwell (Brooklyn, N.Y.), Anna Wlodarczyk (Orange, Calif.) and Bud Held (Del Mar, Calif.) will be among the competitors at the 2005 USA Masters Outdoor Track & Field Championships Aug. 4-7, on the world's only "Rainbow" track at the University of Hawaii in Honolulu. The event will see competition by 800 of the world's best masters track & field athletes, age 30 to 95 years old.

Track events range from 100 meters to 10,000 meters, while field events include the full range of jumps and throws. "World and personal records will be broken on this great track," said meet director and Honolulu resident Mark Zeug. "More than 100 USATF-certified officials, coordinated and assigned by Ron Althoff of Ohio, will be working the meet to ensure a quality experience for the athletes. Equally important, while here in Honolulu, we've made sure that competitors and their families will enjoy a great meet and have the vacation of a lifetime."The meet will include athletes from Australia, Barbados, Bermuda, Canada, Czechoslovakia, Germany, Japan, Romania, Tasmania, the United Kingdom and the United States.

Dr. Macdonald, 56, Oahu's Kailua High cross country and track standout who grew up just ten miles from the Rainbow track in Honolulu, is generally regarded as the greatest runner ever produced in Hawaii. A Stanford alumnus, now an anesthesiologist and cross country and track coach at Honolulu's Punahou High School, Macdonald in 1976 became the first runner to break legendary Steve Prefontaine's American 5,000- meter record with 13:19.40. He competed in the 5,000 at the 1976 Olympics in Montreal and will run the 5,000 on Thursday, August 4, at the 2005 Championships in his first competitive return to the track since recovering from an Achilles injury.

Porter (formerly Trish King before marrying fellow Olympian, distance runner and U.S. cross country champion Pat Porter), one of two women in the world to have jumped 1.76 meters/5-9.25 after reaching the age of 40, heads the field of high jumpers. A neck injury forced Porter, 42, off the track for 11 years, but the 1988 Olympian recovered and set a world record in the 2003 Masters Championships at her alma mater, the University of Oregon.

Barnwell, competing in the men's 45-49 division, hails from Brooklyn, N.Y., and represented Guyana in two Olympics. He brought home gold in the 100 in the last two masters world championships (Puerto Rico, 2003; Brisbane, 2001) and looks to shine on the Rainbow track in the 100 and 200.

Polish Olympian Anna Wlodarczyk, 54, finished fourth in the long jump in the 1980 Moscow Games. Now the coach at Chapman University in California, she won the long jump, triple jump, 80m hurdles, high jump, and heptathlon in the 2003 USA Masters Championships and will be almost impossible to beat in Honolulu.

Franklin "Bud" Held, 77, NCAA javelin champion and 1952 Olympian, was the first to throw the javelin more than 260 feet, breaking a world record in 1953 with a throw of 263 feet, 10 inches. He also improved everyone else's performances by designing an improved and better- balanced javelin.

The 2005 Championships boast world-class athletes spanning all ages, locations and walks of life: from a veterinarian (Dr. Jim Stookey, Potomac Valley, DC Track Club world-record hurdler for men 70-74 from Dickerson, MD) and a California district attorney (Rita Hanscom of San Diego notched 3rd-fastest 200 and 2nd-fastest 60 in 2005 Indoors), to a Mississippi oilman (Emil Pawlik, world-record decathlete 65-69).

Among the prominent entrants:

Trent Lane, 95, the oldest entrant at press time, a farmer who enjoyed a 75-year track and field hiatus, stayed in shape by working on his farm in Baker, La. That regimen that has lifted him to age-group records in the shotput, javelin and discus at the National Senior Games.

Other star competitors include USATF's 2005 BENGAY Masters athlete of the year, Kathy Martin, from Northport, N.Y., the premier 50+ woman in the U.S. in the middle distances;

Nadine O'Connor, the emerging superstar from Del Mar, Calif., who may become the first American over age 60 to break 29 seconds in the 200 dash; David Ashford, the 1981 California state high school champ in the 110-meter hurdles (13.67 seconds), who 22 years later set the world record of 13.73 in the same race for the 40-44 age group;

Aaron Thigpen, who will go after Willie Gault's American masters 40-44 record in the 100 meters (10.73).
