Yes, 12 km per hour can be considered a fast running speed for base endurance training.
Understanding Running Speeds
Whether 12 km/h is "fast" depends on the context and who you're asking. Here's a breakdown:
- Base Endurance Training: For base endurance, or "zone 2" training, 12 km/h is on the faster end. Men typically run between 8 and 10 km/h for this type of training. Good runners reach up to 12 km/h in this zone.
- Individual Fitness Level: For a beginner, 12 km/h would likely be very challenging to maintain for any significant duration. For a seasoned runner, it might be a comfortable, sustainable pace.
- Comparison to Elite Runners: Elite runners often exceed 15 km/h, even reaching up to 17 km/h, so in comparison, 12 km/h is not an elite speed.
Context is Key
The term "fast" is subjective. Considering the purpose and the individual's capability provides the most accurate assessment. For many recreational runners focused on base training, achieving and maintaining 12 km/h is a significant accomplishment.
