How fast can SNSD's HyoYeon run?

We're all excited about SNSD's upcoming episode on 'Running Man' but just before that, HyoYeon is here to show us how fast she is when it comes to running.

Check out her next clip where SooYoung playfully shared, "Crazy Kimyoyeon #euhehehe #dehet #ahheulkheulkheuk by #yoong" to which HyoYeon replied, "ehehey... ㅋㅋㅋㅋㅋㅋㅋㅋ what do you mean crazy, I was excited"~
