Helpful Information
- Pace vs. Speed:
Pace refers to the amount of time it takes to cover a certain distance (usually minutes per mile or kilometer), while speed is the distance covered in a certain time (miles or kilometers per hour). This calculator gives you both to provide a full picture of your running metrics. - Why Splits Matter:
Splits help break down your race into manageable segments, making it easier to maintain consistent effort and evaluate your performance during and after the race. - Custom Distance Use:
Training for a non-standard race distance or long runs? Just select "Custom Distance" and enter your distance in miles to get precise pacing info. - Quarter Distance Splits:
This split option divides your race into four equal parts and calculates the time you should aim to complete each quarter, giving you another way to monitor your pace.
