Pacing Strategies Explained

Even Splits (Recommended for Most Races)

Maintain the same pace throughout the race. This is the most energy-efficient strategy and recommended for distances 200m and longer. Research shows even pacing leads to faster times for most swimmers.

Negative Splits (Advanced Strategy)

Swim the second half faster than the first. This conservative approach ensures you don't fade at the end. Popular in distance events (800m, 1500m) and requires excellent fitness and pacing discipline.

Positive Splits (Sprint Strategy)

Go out fast and hold on. Common in 50m and 100m sprints where anaerobic energy systems dominate. Requires excellent technique to maintain efficiency when fatigued.

How to Use Race Splits

  1. Practice in training: Swim sets at your target split times
  2. Memorize key splits: Know your target times for 50m, 100m, etc.
  3. Use pace clocks: Check your splits during the race
  4. Adjust if needed: Have plan B if you're ahead or behind pace
