How is distance calculated from pace and time?

Distance = Time / Pace. For example, running for 30 minutes at 5:00 min/km pace covers 30/5 = 6 km.

Why does my GPS show a different distance?

GPS watches can have 1-3% error due to signal quality, tree cover, buildings, and update frequency. Track or measured routes are more accurate.

Beginners should start with 2-3 km and gradually increase. Follow the 10% rule — increase weekly distance by no more than 10% per week.
