Frequently asked questions

What's the most important training zone?

Easy pace — where most elite runners spend 70-80% of their weekly mileage. Going too fast on easy days is the most common amateur mistake. Easy running builds aerobic base and fatigue resistance without excessive breakdown.

How often should I run threshold pace?

Once or twice per week in a structured programme. Threshold (tempo) running is the most effective single session for improving 10K and half marathon performance — but it needs adequate recovery.
