Common questions
What can I solve for?
Any one of pace, total time, or distance, given the other two. For example, enter a 10 km distance and a 50-minute time to get a 5:00/km pace, or enter a target pace and distance to get the finish time.
Which units are supported?
Distance in kilometres or miles. Results show pace as both minutes per kilometre and minutes per mile, plus average speed, so you don't have to convert by hand.
How do I enter time and pace?
Time is entered as hours, minutes, and seconds. Pace is entered as minutes and seconds per unit distance. Leave a field at zero if it doesn't apply.
