Frequently Asked Questions
What's a good pace for a beginner runner?
Pace varies widely by fitness level, but many beginners run around 10-12 minutes per mile (6-7.5 min/km), gradually improving with training.
Should I train at my goal race pace?
Training plans typically include a mix of paces — easy runs slower than race pace, and some workouts at or faster than goal pace — rather than running every session at race pace.
How do I convert between min/km and min/mile?
Use the unit selector in this calculator — switching units automatically recalculates your pace in the equivalent format.
Does this calculator account for elevation or terrain?
No, this is a straightforward pace/time/distance calculator and doesn't adjust for hills, elevation, or trail conditions, which can affect real-world pace.
