At the end of the April 23rd broadcast of KBS's "100 Points out of 100", a preview of next week's special episode was revealed. In the preview, it looks like idol members from B2ST, MBLAQ, 4minute, T-ara, Dalmatian, Secret, Block B, ZE:A, and more are coming together for "The National Idol Star Sports Festival". The idols will compete in several challenges such as pull-ups, sit-ups, rollerblade races, and the classic footrace. Park Myung Soo, Lee Gwang Yong, Kim Tae Hyun, and Kim Shin Young will be acting as the commentators, which will add a fun and witty twist to the show. Fans have shown much interest in the past during the special Chuseok and Lunar New Year episodes of MBC's "Idol Athletics Championship". Although this is a much smaller scale to the holiday specials, fans are, nonetheless, showing much anticipation for this episode. This episode is scheduled to air on Saturday, April 30th, so be sure to check it out to see idols compete in rigorous physical challenges. Until then, you can check out the preview below!
