Frequently Asked Questions
What is the relationship between speed and pace?
Speed is distance divided by time (e.g. km/h), while pace is time divided by distance (e.g. minutes per km). They are inverse reciprocal measurements.
What is a good 5K pace for recreational runners?
A common recreational 5K time is between 25 and 35 minutes, representing a pace of 5:00 to 7:00 min/km (8:00 to 11:15 min/mile).
