The "starting line" is a designated point in a race where participants begin their competition. It is often marked by a physical line on the ground, which can be made of tape, paint, or other materials. Races can vary in distance and type, including sprints, marathons, and triathlons, but all share the common feature of a starting line. At the starting line, athletes typically gather before the race begins, often following a countdown or signal from a race official. The starting line is crucial for ensuring a fair start, as all competitors begin from the same point, allowing for an equal opportunity to compete.
