The signature races in Gwinnett Bike Fest's final day were as hot as the mid-90 temperatures at the Gwinnett Progress Center near Lawrenceville.

And it was a 15-year-old from Suwanee who may have made the biggest impression.

David Goodman, a rising freshman at Collins Hill High School, won two races Sunday on the 2.7-mile loop circuit course that hosted nine races of varying lengths and skill levels.

After winning the Junior 15-16 age division in the morning, Goodman blew away the field in the men's Category 4-5 race in the afternoon. He took the lead with two laps to go and was literally forgotten about by the rest of the field.

Goodman's margin was so wide —- about 9 seconds over the rest of the pack —- that second-place finisher Santana Wilkinson of Stanley, N.C., didn't realize he wasn't the winner until the top three riders were to step on the podium for their awards. It was Goodman's first win in a men's race and the first on his team from Suwanee-based Frazier Cycling, which dominated the youth races in the four-day, four-stage race.

"I just caught up [to the group] and went around them and kept pedaling," Goodman said. "It's the first time any of us has done it, so it shows it can happen. . . .

"I just hope none of [the older racers] get mad at me," he added with a laugh. "Most of them are pretty nice, though. Very supportive."

The top races —- men's Cat 1-2 and men's Cat 3 —- both came down to the wire Sunday.

Frank Travieso, a native of Havana, Cuba, now residing in Athens, pushed past Edgardo Richiez of Yauco, Puerto Rico, and Facundo Bazzi of Norcross at the finish in the men's Cat 1-2, which raced 90 minutes on the course, the longest race of the day. Cesar Grajeles, a Rock Racing team member from Athens, won the overall title.

In the Cat 3 race, John Alvarez of Hilton Head Island, S.C., nipped Shane Byler of Mableton at the finish.

Sunday also was a big win for organizers of the second-year race. According to Pete Sherrard of the Gwinnett Sports Commission, 932 riders participated in the race, up from just over 500 last year.
