Running consistently from 5K to marathon while building endurance, form, strategy, and injury prevention.
Running encompasses proper form, structured training, injury prevention, nutrition, and race strategy. Progress is measurable through distances completed, pace improvements, and race finishes, with established benchmarks at every stage of development.
Age/gender-based Beginner-Novice-Intermediate-Advanced-Elite 5-tier performance classification with distance-specific (5K-marathon) benchmark times, directly used for level boundary calibration.
Weekly mileage progressions and long-run benchmarks across Novice-Intermediate-Advanced tiers directly inform checklist items for distance, frequency, and duration criteria at each level.
Tier 0-5 training volume and performance criteria scientifically underpin observable checklist standards (distances, paces, qualifications) across all seven levels.
Official competition rules, anti-doping standards, and elite event qualification requirements from World Athletics, serving as the authoritative source for upper-level competition benchmarks.
