Allyson Felix anchored the Kersee All-Stars' winning 400-meter relay team in a surprise appearance Saturday in the Mount San Antonio College Relays.
"It's just a fun meet," said Felix, the Olympic champion from Los Angeles. "I've ran here since high school, I just enjoy it. It's the only time that my family who are here can come out and support me."
She helped the team finish in 43.10 seconds.
"I haven't done any speed (conditioning) yet," Felix said. "But it feels good to get moving."
Felix won a gold medal in the 400 relay in the 2008 Beijing Olympics and finished second in the 200.
After the race, she posed for pictures and signed autographs for the star-struck teenage athletes.
"It's cool to get to see the high school girls," said Felix, who turned professional after graduating from high school in 2003. "I remember when I was in that same position. It's fun just to get back."
Two-time Olympic medallist David Neville raced for the first time this season, finishing fifth in the 400 in 44.61. He's returning from an Achilles' tendon injury.
"I actually feel a lot more confident after being able to run as well as I did than I was coming into this race," he said.
In other events, Jesse Williams matched his national season best in the high jump at a meet-record 7 feet, 8 inches, and Carmelita Jeter won the women's 100 in 10.99 — also the best in the nation this year.
College stars Charles Jock and Bryce Brown also had national bests. Jock, a junior at UC Irvine, won the 800 in 1:45.19, and Texas Tech's Brown took the 400 hurdles in 49.25.
