Not that we need another reason to watch the next episode of SBS' 'Running Man', but guests SISTAR's Bora and Soyu, AOA's Seolhyun, A Pink's Bomi, and�Lee Kuk Ju look like they're having the time of their lives in the released preview!

This episode is going with the concept 'Queen of Summer' where the guests will go on a race to claim that title. In the teaser you can see the girls show their aegyo, dance, go to a waterpark, eat delicious food, and physically battle it out to become the 'queen'! At one point, even Bora's hair extension falls off (or gets pulled off)!
