How to use Kaizen

Kaizen takes a unique approach to training that lets you focus on what really matters: running consistently over time. 

The Prediction

Running performance can be accurately predicted by analysing an athlete’s overall training load and prior race history. If you can accurately predict performance based on training, then you can dictate training to achieve a certain result. Kaizen is built around this concept.

Kaizen’s training system is based on an algorithm, which accurately predicts race performance for 93% of race results for 5k, 10k, half marathon and the marathon. The system has been trained on millions of data points from thousands of runners.

For most races Kaizen is able to predict your race pace to within 2sec/km - meaning you will know exactly what speed to run at to achieve the best possible result.

Training with Kaizen

Once you’ve connected your data and set a goal, you will be set a weekly distance target.


The weekly target may change during the week, depending at what pace you run, how much elevation you gain and how much cross training you do.


Your race prediction will update after every run, considering the impact of every single run on your overall fitness. If you achieve your weekly target week after week, Kaizen will get you in shape to run your goal time on race day and you'll see your prediction improving accordingly.


Kaizen reflects an accurate picture of your training and progress. Its simplicity keeps you motivated and realistic about achieving your running goals.

Kaizen's race predictions are accurate for 93% of races to within 5s/km. The predictions are best used as pacing guidance and feedback about how your fitness is progressing.

Kaizen's predictions are for a ‘best case’ scenario. This means that to match (or beat) your race prediction you’ll need to race:

- at maximum effort

- on a flat road

- with good pacing

- in good weather
