Frequently Asked Questions
How do I calculate pace?
Divide total time by distance. For example, 30 minutes over 3 miles is 10 minutes per mile.
What is the difference between pace and speed?
Pace is time per unit distance. Speed is distance per unit time.
Should I use moving time or elapsed time?
Use elapsed time for race estimates. Moving time can be useful for training logs when stops are not part of the effort.
Why does GPS pace jump around?
GPS can be noisy over short intervals, around buildings, or on winding routes.
Can I use this for walking or cycling?
Yes. Any activity with distance and time can be converted into pace and speed.
