How do I use a pace conversion chart?

Find your current race pace (e.g., 5K), then look across the chart to see predicted times and paces for other distances like 10K, half marathon, and marathon.

Is a pace chart accurate for marathon predictions?

Pace charts offer a general guide based on equal effort but don’t account for endurance, fueling, or fatigue. Use Kaizen’s dynamic predictions for more accuracy.

Can Kaizen convert pace between distances automatically?

Yes, Kaizen provides a built-in race pace chart and calculator that automatically converts pace between race distances and gives you personalized training insights.

What if I don’t know my exact pace?

You can input a recent race time into the Kaizen calculator to find your average pace and see predictions for other distances based on that effort.

How does Kaizen update my pace chart over time?

Kaizen syncs with your Strava activity data and adjusts your predicted race paces and chart conversions automatically as you log more runs.
