Frequently Asked Questions
What is a good running pace for beginners?
Beginners often run 10-14 minutes per mile (6-9 min/km). Focus on completing the distance first before worrying about speed. A conversational pace where you can talk while running is ideal for building endurance.
How do I calculate my pace?
Divide your total time by the distance. For example, 30 minutes for 3 miles = 10 minutes per mile. Convert to seconds for more precision.
What pace do I need for a sub-4 hour marathon?
To finish a marathon in under 4 hours (26.2 miles), you need to maintain a pace of about 9:09 per mile or 5:41 per kilometer.
How accurate are race time predictions?
Predictions assume similar training and conditions. Longer races are harder to pace evenly. Add 5-10% to predicted times for races you have not run before.
