Frequently Asked Questions

What is a good running pace for beginners?

For beginners, a good running pace is one where you can maintain a conversation while running. This typically ranges from 9-12 minutes per mile (5:30-7:30 per km). Focus on consistency and gradually building endurance rather than speed initially.

How do I calculate my target marathon pace?

Your marathon pace should be 30-60 seconds per mile slower than your 10K pace, or about 15-30 seconds per km slower. Use recent race times with our Finish Time Predictor to estimate your marathon pace, and practice running at this pace during long training runs.

What's the difference between pace and speed?

Pace is time per distance (e.g., 6:00 per mile), while speed is distance per time (e.g., 10 mph). Runners typically use pace because it's easier to maintain a consistent effort level and plan race strategies.

How should I pace different race distances?

5K: Start slightly slower than goal pace, build in middle, finish strong. 10K: Even pacing throughout. Half Marathon: Start conservatively, negative split if possible. Marathon: Even pacing is crucial, save energy for final 10K.

What factors affect my running pace?

Weather (heat/humidity slow you down), terrain (hills and trails are slower), altitude (higher elevation reduces pace), fatigue level, hydration, and nutrition all significantly impact your running pace. Track your calories burned to optimize your nutrition strategy.

How do I determine my training paces?

Training paces vary based on your fitness level and workout type. Use our Training Paces Calculator to get personalized pace recommendations for easy runs, tempo runs, intervals, and long runs based on your recent race performance.
