What pacing strategy is typical for a 400 m freestyle and why?

• A. Start fast and hold pace
• B. Random pacing
• C. Even pacing or slight negative splits
• D. Start slow

Answer: (C)

The main idea is pacing for a middle-distance freestyle: you want to manage energy so you can maintain a smooth, sustainable tempo throughout the race. A 400 m event relies heavily on aerobic energy, with some contribution from anaerobic systems. If you start too fast, you burn through your energy reserves early, leading to a fade in the last 100 m. If you start too slowly, you’re left trying to make up time later, which is inefficient and tiring.

Therefore the typical approach is to swim with even pacing—keeping each 100 m split roughly the same—or with slight negative splits, finishing the final portion a bit faster than the first. This distributes effort evenly, preserves stroke technique and efficiency, and supports a controlled, strong finish. Random pacing or starting very slow tend to waste energy and reduce overall performance.
