Pacing Strategy Guide

Even Splits: Maintain the same pace throughout. Most reliable strategy for achieving your goal time. Best for experienced runners who know their limits.

Negative Splits: Run the second half faster than the first. Conservative approach that reduces the risk of hitting the wall. Requires discipline to hold back early.

Positive Splits: Run the first half faster than the second. Riskier strategy that can lead to significant slowdown. Only recommended if you're very familiar with the distance.

Tip: Add 5-10 seconds per km to your target pace for the first few kilometers (depending on the race) to account for race-day excitement and crowding at the start.
