Frequently asked questions

What is a good 5K pace?

A "good" 5K pace depends on experience and age. The useful thing is consistency: use your current 5K time to set training paces you can repeat week after week.

Should easy pace feel slow for 5K training?

Yes. Easy pace should feel conversational. It builds aerobic fitness and lets you recover so you can hit your harder workouts.

How often should I update my 5K training paces?

Any time you run a meaningful PR or your fitness changes (often every 4-8 weeks in a training block).
