RU:SH is a running crew made up of past and current students from three universities in Sinchon, Seoul. It was founded in 2015 by Yoonjin, who wanted to cultivate a running community in the area by connecting students among nearby campuses.

Together, RU:SH aims to spread the university running culture to young runners in Seoul through various collaborations with other running crews and by maintaining a fun and supportive group of friends who love to run!
