FAQ
How are the predicted times calculated?
They're a simple projection assuming you could hold the same pace for 5K, 10K, a half marathon, or a full marathon. In reality, pace tends to be harder to sustain over longer distances, so treat these as rough estimates.
Can I use this with a treadmill's readout?
Yes, enter the distance and time shown on the treadmill display to calculate your pace the same way.
How is the mile-to-kilometer conversion done?
It uses 1 mile = 1.60934 km.
