25M Beginner Benchmark Reality

Untrained adult men (zero prior athletic foundation) frequently believe their baseline is "terrible" because social media and high school memories distort expectations.

Category 1-Mile Pace Physiological Reality
High School Sprint / Myth 6:30 - 7:30 /mi Anaerobic redline; 95% of beginners gas out before 600m.
True Untrained 25M Average 11:00 - 13:45 /mi Healthy baseline! Cardiac stroke volume adapting to sustained load.
Walk-Run Interval Pace 12:30 - 14:30 /mi Gold standard for building capillary density without injury.
12-Week Adapted Base 9:30 - 10:45 /mi Achieved with 80% easy volume and zero bone stress fractures.
