Approximately 10,000 athletes marched in Saturday's parade of athletes as Gay Games 2010 officially kicked off inside Cologne, Germany's RheinEnergie Stadium.

The week-long celebration of sport opened with an amazing 2-hour program that featured Matthew Mitcham, the 22-year-old openly gay Australian Olympic gold medal diver, speaking the oath of the athletes, and performances by gay icon Taylor Dayne and Swedish Idol winner Agnes Carlsson.

Surrounded by fire dancers, Dayne closed the ceremonies with a performance of her new song, Facing a Miracle, to benefit the games.

Germany's openly gay foreign minister, Guido Westerwelle, presided over the celebration.

Gay sports website Outsports is reporting that competition began on Sunday with cycling, skating and a triathlon.

“The 30+ sports kick off Sunday. There is a cluster of about half of them located in the same area as the Opening Ceremonies were held. It will make it super-convenient for fans and athletes to see a lot of sports in a short time; it's a terrific idea for what we hope is a terrific event,” site owner Jim Buzinski wrote.

Cleveland, Ohio is scheduled to host the 2014 iteration of the games, but irregularities in the city's bid prepared by the Cleveland Synergy Foundation have threatened the group's participation in sponsoring the event. The Cleveland Plain Dealer reported Friday that Synergy representatives were noticeably absent from the city's delegation traveling to Cologne. But Synergy has vowed to fight on. In a statement released Friday, the group said it was sending a four-man delegation to receive the Gay Games' flag during the games' closing ceremony, as planned.
