Assess ability to design a comprehensive, evidence-based 12-week periodized program for competitive 800–1500 m runners that integrates training (macro- and microcycles, intensity distribution, strength/power, plyometrics), nutrition (energy availability, periodized fueling, race-week strategy), recovery (sleep, regeneration modalities, load management), monitoring metrics (training load, HRV, RPE, lactate, GPS, wellness surveys) and clear contingency/decision rules for illness, overtraining, or injury; include rationale, a sample weekly microcycle, and specific monitoring thresholds and return-to-training plans.
