Calculate your pace per mile or kilometer, predict race times, and analyze your running or walking performance

Whether you're training for a race or tracking your fitness walks, our pace calculator helps you understand your performance. Calculate your pace per mile or kilometer, convert between pace and speed, and project finish times for popular race distances from 5K to marathon.
Pace is the time it takes to cover one unit of distance (e.g., 8:30 per mile). Speed is the distance covered per unit of time (e.g., 7 mph). Runners typically use pace because it's easier to maintain a consistent effort. Our calculator shows both metrics and predicts race times based on your current pace.

Calculate your pace after a run to track improvement over time.
Monitor walking pace for fitness tracking and daily exercise goals.
Convert treadmill speed settings to outdoor pace equivalents.
Most beginners run between 10-13 minutes per mile (6-8 min/km). Focus on completing the distance comfortably rather than speed. As fitness improves, pace naturally decreases.
Projections assume you maintain the same effort level and have trained appropriately for the longer distance. Real race times depend on training, course terrain, weather, and race-day factors. Use them as general targets.
A sub-4-hour marathon requires an average pace of 9:09 per mile or 5:41 per kilometer. That's maintaining about 6.55 mph for 26.2 miles.
Yes! You can typically hold a faster pace for shorter distances. Many runners are 30-60 seconds per mile slower in a marathon than a 5K. Use this calculator to understand the difference.
Pace is time per distance unit (min/mile). Cadence is steps per minute (SPM). They're related but different. Optimal cadence for most runners is 160-180 SPM, regardless of pace.
