About this app

Welcome to Kaizen, your data-driven training partner that will help you unlock a new PB.

A DYNAMIC WEEKLY DISTANCE TARGET
Each week you get a simple, dynamic distance target. Under the hood it is the training load that you can sustainably achieve for the week, translated into a distance based on your average intensity and cross-training for previous weeks. If you run harder because you’re feeling good, the distance you’ll need to run decreases. If you run easier because you feel like that’s what your body needs, you can still achieve the same training load by running further.

HIT YOUR TARGET EACH WEEK AND ACHIEVE YOUR GOAL
As long as you achieve your weekly distance target each week, you’ll be in goal shape by race day. If you don’t manage the consistency because life, you’ll still know the exact shape you’re in so you can race with confidence.

Ratings and reviews

I like the idea of it , need more time to see if the data is helpful for me. At the moment , the user interface is not good enough to be expecting paid subscription. The week planner needs some improvement ,on my device when it is dragged to the bottom,when it i reopened the info never loads. Id also like the option to add several weeks ahead.

the ui is just trash feel like if i had access. to the code for a week i could do a better job - and yes i am a software developer that hates writing uis not sure what the donut represents and what you need me to do to fill it it says if i out in more effort then it fills more then why is it a distance goal im so confused, feel like it needs an into or an example. some sort of free version of the app would help immensely even if it was slimmed down because having to pay 80£ a year is too muc

the core algorithm is really neat, I like how simplified it is in terms of teaching training load and not bogging you down with heaps of noise and distracting stats. the only reason I'm docking a star is that the data sometimes just disappears when I check the app, even when it has previously been there, like it switches a previous workout to a rest day. I don't know if this is a Strava integration issue or what but usually if I restart the app a few times, or check back later, it looks correct.
