Understanding Pace, Time, and Distance

For any endurance athlete, the relationship between pace, time, and distance is fundamental. Pace is a measure of speed, typically expressed as the time it takes to cover a specific distance (e.g., minutes per kilometer or minutes per mile). This calculator is a flexible tool that allows you to solve for any one of these three variables if you know the other two.

How to Use the Calculator

First, select the value you wish to calculate: Pace, Time, or Distance. The calculator will automatically adjust the input fields, disabling the one you are solving for.

• To Calculate Pace: Enter your total time and the distance you covered. The calculator will show you your average pace per kilometer and per mile.
• To Calculate Time: Enter a target distance and your desired pace. The calculator will predict your finish time and provide a split chart for each kilometer or mile. This is perfect for race planning.
• To Calculate Distance: Enter your total time and your average pace. The calculator will estimate how far you traveled.

Why Pacing is Important

Proper pacing is one of the most important skills for endurance events like marathons, long-distance cycling, or triathlons. Starting out too fast is a common mistake that can lead to exhaustion and a slower overall finish time. By using this calculator to plan your race, you can determine a realistic and consistent pace that you can maintain throughout the event. The splits table generated by the calculator is especially useful, as it gives you target times to aim for at each kilometer or mile marker, helping you stay on track from start to finish.

Common Race Distances

Here are some standard running race distances to help you use the calculator:

• 5K: 5 kilometers or 3.1 miles
• 10K: 10 kilometers or 6.2 miles
• Half Marathon: 21.1 kilometers or 13.1 miles
• Marathon: 42.2 kilometers or 26.2 miles
