Frequently asked questions

What is a good running pace?

Recreational runners typically run 5:30–7:30 per km. Beginners often start near 8:00/km; sub-4:00/km is competitive amateur territory.

How are race projections calculated?

Projections hold your current pace constant. Real marathons typically slow 2–5% versus 5K pace due to fatigue and fueling.

Is pace per km or per mile shown?

Both — every result displays pace per kilometer and per mile side by side, whichever your watch or race uses.
