V. Frequently Asked Questions
Q: Is 8 weeks enough?
A: If you already have a solid 10K base, 8 weeks is sufficient to finish and perform steadily. If you aim for a PB, a 12 to 16-week plan is recommended.
Q: Can I skip the recovery week?
A: Not recommended. The recovery week is crucial for allowing the body to supercompensate; skipping it increases injury risk.
Q: What to do if minor discomfort occurs during training?
A: Immediately reduce training volume, observe for 2 to 3 days. If discomfort persists, seek medical attention. Do not run through injury.
