If you have ever been at the finish line of an obstacle race or mud, run you have probably heard someone utter those words after crossing the finish line caked in mud, bruised, and often bleeding from a scrape earned while on the course. We have all felt it at one time in our racing career, that rush of excitement after a, particularly challenging obstacle. We have all seen that face that a fellow racer makes when they finally get over that 8-foot wall or climb that rope. It's that intangible sense of excitement that can hardly be described and truly only felt by the participant.
