What is UOR? Urban Obstacle Running (UOR) was born on the streets of Stellenbosch, South Africa. UOR is to Parkour and Freerunning what MMA is to martial arts. It combines classic parkour with urban trail running, tricking & free-running to culminate in creating a fun new way in which to get fit and get over obstacles, in sport as in life.
