Key Considerations
- A 30-minute 5K requires a pace of 6:00/km (9:39/mile)
- A 25-minute 5K requires 5:00/km (8:03/mile)
- A sub-20 5K requires under 4:00/km (6:26/mile) — this is competitive club-level
- Most 5K improvement comes from increased easy running volume, not speed sessions
- The 5K uses approximately 90% aerobic and 10% anaerobic energy systems
Specific Adjustments
Beginner (30+ min)
Focus on completing the distance first. Run at conversational pace with walk breaks as needed.
Intermediate (20-30 min)
Add one tempo run and one interval session per week. Most runs should still be easy pace.
