Obstacle Course Races (OCR) are competitive events that combine running with various physical challenges. Participants navigate through a series of obstacles, which may include climbing walls, crawling under nets, and jumping over barriers. These races can vary in distance and difficulty, appealing to a wide range of fitness levels. OCRs are often held in outdoor settings, such as parks or rugged terrains, and can be organized as individual or team events. Popular examples of OCRs include the Spartan Race and Tough Mudder. These races promote physical fitness, teamwork, and mental resilience among participants.
