the.com/obstacle course

means A series of physical obstacles — walls, nets, ditches, bars — that you must climb, crawl, or vault through, usually against a clock, to test agility and endurance.

from From Latin obstaculum, 'something that stands in the way,' built from ob- ('against') plus stare ('to stand') — the same stare root that gives us 'stand' and 'statue.' The 'course' is from Latin cursus, 'a running.' Military training grounds popularized the combined phrase in the 20th century, turning 'things standing in your way' into a formal, timed gauntlet — eventually exported from boot camps to gym class and reality TV.
