Even Splits vs Negative Splits
Common Race Paces

Estratégia

Negative split: 2ª metade mais rápida — estratégia dos elites. Comece 5-10 seg/km mais lento que o pace-alvo. Even split: pace constante — mais fácil de gerenciar. Positive split: mais lento no final — sinal de largada rápida demais.

Por Distância

5K: pace-alvo desde o início. 10K: 5 seg/km mais lento no km 1. Meia: 10 seg/km nos 3 primeiros km. Maratona: 10-15 seg/km nos 5 primeiros — a paciência aqui salva o "muro" dos 30 km.

⚡ CalcWolf Insight

The marathon "wall" at mile 20 is not inevitable — it happens because runners deplete glycogen stores by going out too fast. Even-split or negative-split strategies, combined with proper fueling (30-60g carbs/hour during the race), can eliminate the wall entirely. Most 3-hour marathoners feel strongest in the final miles because they paced correctly.

Frequently asked questions

Positive ou negative split?▾

Negative (terminar mais rápido) é ideal. Comece conservador e acelere gradualmente.

Maratona?▾

5 primeiros km LENTOS. Estabilize no km 8. Acelere no 30 se se sentir bem. NUNCA siga a multidão no km 1.
