Pace, time, and distance.
These calculators use established formulas (such as Mifflin-St Jeor for calorie needs or the Devine formula for ideal weight) to provide general estimates. They're built for a general population and don't account for individual medical conditions, medications, or circumstances. They aren't a substitute for advice from a doctor, registered dietitian, or other qualified healthcare provider — especially for anything related to pregnancy, chronic conditions, or medication dosing.
Pace = time / distance. Convert to km/h by dividing 60 by min/km.
Plan target race pace or check what pace your recent run works out to.
Knowing your pace precisely matters most for race-day pacing strategy — starting even slightly faster than sustainable pace is one of the most common ways runners fade in the second half of a race.
5 km in 25 min = 5:00 min/km, or 12.0 km/h.
6:30–8:00 min/km is normal for easy runs. Focus on distance and consistency before speed.
Multiply by 1.609. So 5:00 min/km ≈ 8:03 min/mile.
No — most training runs should be noticeably slower than target race pace, with only a small portion of weekly volume at or near race effort.
