Marathon Negative Splits Blueprint: 42.195km Kilometer Pacing Execution

Over 95% of world marathon records are set utilizing negative splits (running the second half 1-3 minutes faster than the first).

Conserving glycogen during the initial 21.1km prevents premature Type IIb muscle fiber recruitment, unlocking surge capacity beyond 35km.
