When asked if she doesn't find 'Running Man' tiring, Song Ji Hyo said, "Though it is really tiring, I've done 'Running Man' for 4 years, so I'm used to it by now. Now I think I can enjoy it. Even if I'm sleepy, I end up enjoying it. I'm able to [act and appear on a variety show at the same time] by choosing to sleep and eat a little less."�

As for her 'Running Man' castmate Gary�and his appearance on her past drama 'Emergency Couple', Song Ji Hyo expressed how thankful she was. She said, "I was so thankful that he gave it his all despite the fact that it was a small role. Though he didn't have any lines, he was the best at his ad-libs and being natural. I give him a 10 out of 10 for completely devoting himself to the character."
