MBC's special titled, "Idol Athlete Competition," started in anticipation for the 2012 London Olympics. The sports featured in the olympics like archery, fencing, and ping pong were all included in this idol competition.

Jo Kwon and Kim Dong Joon competed head to head in the 100m Track Race.

In this particular episode, 'Silly Sign Bolt' Jo Kwon, 'athlete idol' Kim Dong Joon, and short track winners B1A4 all got together to compete.

Everyone was especially interested to see how Jo Kwon and Kim Dong Joon would do. Both had displayed very competitive attitudes even before the games.

Right after Kim Dong Joon crossed the finish line for the 100M track, he asked what Jo Kwon's time was. His fiery competitive nature was like any actual olympic athlete's.

It was also discovered that in the midst of all this competition, an unexpected rookie rose as dark horse. He flustered the athletes and the viewers.

The results for the "athlete idol" games will be revealed on episodes to be aired on July 25 and 26.
