Frequently Asked Questions

What is a good 5K pace?

A beginner runner averages 7-8 minutes per kilometer. Intermediate runners achieve 5-6 min/km. Elite runners run under 3 min/km.

How accurate are race predictions?

Predictions assume you can maintain the same pace across all distances. In reality, longer races require slightly slower pacing. Use predictions as a rough guide.

How do I improve my running pace?

Mix easy runs, interval training, tempo runs, and strength work. Most runners improve by gradually increasing weekly mileage and including one speed session per week.
