About this app

kaizen helps you understand what your training is building toward, because training plans break when life gets in the way

Connect Strava or Garmin and kaizen turns your recent training and race history into clear guidance for the week ahead. See what your current training suggests is possible, train toward your goal with more confidence, and build consistency without losing sight of real life.

Train for a 5K, 10K, half marathon or marathon — or train at a rate of improvement that helps you keep getting better over time.

Whether you’re building toward race day or focusing on steady long-term progress, kaizen helps you train with more context, more clarity and less noise.

CHOOSE HOW YOU WANT TO TRAIN

The first training systems in kaizen give you more structure and guidance without the brittleness of a rigid plan.

Start with:

- Blank Canvas for full flexibility
- Even Spread for a calm, repeatable weekly rhythm
- 1 Long, 1 Hard for a week anchored by one longer run and one harder effort

You choose the structure that fits you. kaizen adapts the work underneath based on your current fitness, goal and timeline.

WHAT YOU GET

- Race predictions for 5K, 10K, half marathon and marathon
- Guidance shaped by your recent training and race history
- Flexible weekly training that adapts to the running you do
- More structure without being locked into a plan that breaks when life gets in the way
- Clearer confidence about the shape you are in before race day
- A way to train not just for one race, but for steady long-term improvement

BUILT AROUND CONSISTENCY

kaizen is built around a simple idea: improvement comes from enough good work, repeated consistently, for long enough.

The point is not to blindly obey numbers or feel like you’ve failed the week because life got in the way. The point is to understand the bigger picture, stay consistent, and make better decisions over time.

Some weeks will be smooth. Some will be messy. Missing a run or having a rough patch does not erase the work. kaizen helps you stay oriented, return well, and keep building.

Because the best training is not the most ambitious plan on paper. It is the training you can actually absorb alongside work, family, stress, sleep, travel and everything else that affects running.

DESIGNED FOR REAL LIFE

Some runners want full freedom. Some want a steadier rhythm. Some want more weekly shape. kaizen is designed to support different ways of training while keeping the same adaptive logic underneath.

The goal is not perfect compliance. The goal is durable progress.

STRAVA OR GARMIN REQUIRED

kaizen adapts based on the running you do, so it requires a data connection to update based on your actual training. It’s currently compatible with Strava and Garmin. You’ll need to connect your Strava or Garmin account for kaizen to analyse your activities and calculate your predictions and training guidance.

kaizen does not process or store location or heart rate data.

Ratings and reviews

Great data, it gives me confidence that my training load is appropriate for my goals. Went for a free trial but had to reach out to support, support was near instantaneous in their responses. While they might be an AI based for the training, but support is real humans. Very much appreciated! If youre on the fence, definitely give it a try!

Latest update broke the miles conversion. Units change but the value doesn't. The concept behind this app is neat, but it's incredibly sluggish on Android and the massive intra-week swings in mileage targets make it effectively useless for planning out a week. There's something interesting here, but the execution is lacking

I can't understand why you would pay so much for an app that's only real function is to predict times. Thought it would help map out topline volume planning for a training cycle but it doesn't even do this. Poor interface also doesn't help.
