Frequently Asked Questions
Everything you need to know about our pace calculator
How do I calculate running pace?
Time / Distance. 30-min 5K = 9:41/mile or 6:00/km.
Pace = Time / Distance. For a 30-minute 5K: 30 min / 3.1 miles = 9:41/mile. Or 30 min / 5 km = 6:00/km.
What is a good running pace?
Recreational: 10-12 min/mile; Intermediate: 8-10; Advanced: 6-8.
Varies by fitness and experience. Average recreational: 10-12 min/mile. Intermediate: 8-10 min/mile. Advanced: 6-8 min/mile. Elite: under 5 min/mile.
How do I convert between min/mile and min/km?
min/mile × 0.621 = min/km. 10:00/mile = 6:13/km.
Multiply min/mile by 0.621 to get min/km. Or multiply min/km by 1.609 for min/mile. 10:00/mile = 6:13/km.
What pace should I run a marathon?
1-2 min/mile slower than your 5K pace.
Marathon pace is typically 1-2 min/mile slower than 5K pace. If your 5K pace is 9:00/mile, aim for 10:00-10:30/mile marathon pace.
