Using Fitness Calculators
Pace is usually expressed as time per mile or kilometre, while speed expresses distance per unit of time. Use the calculator that matches how your training plan or race target is written.
Enter the requested values carefully, keep units consistent and review the formula, assumptions and supporting result details shown by the selected calculator.
Fitness calculations are planning tools. Terrain, weather, fatigue and individual conditioning can make actual training or race performance differ from a mathematical estimate.
