Taken from Allkpop:
On August 27th, MBC’s third ‘Idol Star Athletics Championships’ kicked off at the Jamshil Stadium amidst the roar of 10,000 fans.
Hundreds of idols gathered to compete against one another in numerous athletic activities. The program was led by anchorman Oh Sang Jin, Kim Je Dong, Yoon Yeo Choon, and Boom. The opening event began with Mighty Mouth’s Shorry, who parodied the ‘hoop boy’ from the ‘88 Seoul Olympics; this was then followed by Boom Academy’s parody of Stevie Wonder.
The male 100m preliminary race was the first athletics event of the day. 10,000 fans roared in support of Super Junior, INFINITE, Dalmatian, B1A4, ZE:A, Mighty Mouth, MBLAQ, SHINee, TEEN TOP, Hwanhee, gagman Kim Kyung Jin, David Oh, Baek Chung Gang and many others.
The event will be aired around Chuseok. This year Chuseok is on September 12th. I read the event will air on September 13th and I’m guessing it will be on MBC since it’s “MBC’s third ‘Idol Star Athletics Championships'”
