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