What Makes You Faster

Training Element Why It Works
Intervals (400m–1km) Improves VO2max and running economy
Tempo runs Raises your lactate threshold — you can hold a faster pace for longer
Long easy runs Builds aerobic base and endurance
Rest days Where the actual adaptation happens

Race Day Strategy

  1. Don't start too fast — first km should feel easy
  2. Settle into pace — km 2–3 at target pace
  3. Push from km 4 — this is where you dig in
  4. Sprint the last 400m — empty the tank
