What does a sub-three marathon require?

A sub-three marathon means averaging about 6:52 per mile or 4:16 per kilometer for the full distance. That arithmetic is simple; sustaining it requires specific endurance, fueling and consistent training. Start with recent race evidence and the week you can protect. A fast short race supplies context, rather than proof of marathon readiness.

Should every workout follow goal pace?

No. Training intensity should reflect current fitness and the purpose of the session. Goal pace is a useful reference for selected practice, not the definition of easy running.

What would make me revise the target?

A block that cannot be sustained, poor recovery or race-specific practice that does not support the target. Revise the race plan rather than trying to make one heroic session erase the evidence.

What should I rehearse?

Fueling, equipment and controlled effort late in a suitable long session. Choose a rehearsal that fits the block; do not turn every long run into a marathon attempt.
