Assess students' ability to design a season-long periodized training, nutrition, and injury-prevention plan for a high-school distance runner targeting a 5K PR while minimizing overuse injury risk; responses must include meso- and microcycle structure, progressive mileage/intensity, intensity distribution, strength and cross-training, recovery and sleep strategies, caloric and macronutrient guidance (including iron/hydration considerations), monitoring metrics (RPE, HR, training log), injury-prevention screening and interventions, and clear modification/return-to-run criteria with physiological rationale and safety considerations.
