Understanding Pace
What is Pace?
Pace is the time it takes to cover a specific distance, typically expressed as minutes per mile or minutes per kilometer.
Pace vs Speed:
While pace measures time per distance, speed measures distance per time (mph or km/h). They are inversely related.
Training Applications
Easy Runs:
Should be 1-2 minutes per mile slower than your 5K pace. Used for building aerobic base.
Tempo Runs:
Comfortably hard pace, typically 25-30 seconds per mile slower than 5K pace.
Interval Training:
Short, fast segments at or faster than 5K pace with recovery periods.
Common Race Distances
5K: 3.11 miles (5 kilometers)
10K: 6.21 miles (10 kilometers)
15K: 9.32 miles (15 kilometers)
Half Marathon: 13.11 miles (21.1 km)
Marathon: 26.22 miles (42.2 km)
50K Ultra: 31.07 miles (50 km)
Pace Conversion Tips
• To convert mile pace to km pace: multiply by 0.621
• To convert km pace to mile pace: multiply by 1.609
• A 6:00/mile pace equals approximately 3:44/km
• A 5:00/km pace equals approximately 8:03/mile
• Use consistent units for accurate training planning
Frequently Asked Questions
How accurate are pace predictions?
Pace predictions are estimates based on current fitness. Actual performance depends on training, weather, course difficulty, and race day conditions.
Should I train at race pace?
Most training should be at easier paces. Race pace training should be limited to specific workouts and race simulation runs.
How do I improve my pace?
Consistent training with a mix of easy runs, tempo runs, intervals, and long runs will gradually improve your pace over time.
