kaizen is load-based run training for committed runners, starting with the running you have already done. Connect Strava, Garmin or Apple Health so kaizen can analyse your training and race history. See how your fitness is developing, what shape you are in now and what your training suggests is possible. kaizen then connects that picture with your goal and timeline to map the weekly training load needed ahead. kaizen does not process or store location data. Train toward a 5K, 10K, half marathon or marathon—or set a rate of improvement without an upcoming race. CHOOSE HOW YOU TRAIN Use a suggested training structure or build the week yourself: • Even Spread for a calm, repeatable weekly rhythm • 1 Long, 1 Hard to anchor the week around one longer run and one harder effort • Build Your Own for complete control over the week Choose structured workouts, plan your runs and see how each session contributes to your weekly target. ADAPT AS YOU GO Move or edit sessions when the week changes. Every completed run recalculates both your current fitness and the training load needed ahead. HOW LOAD WORKS Equal distances do not always represent equal training. kaizen uses distance, pace and elevation—along with supported cross-training minutes—to understand the load created by different activities. This keeps the bigger picture consistent while giving you control over how the work gets done. Start with a seven-day free trial.

Verdict

The call

The clearest difference is rating: kaizen | Adaptive Run Training at 4.8 against Lactate Training's 4.0. kaizen | Adaptive Run Training also leads on ratings volume (29 vs 2). Lactate Training's advantage is monetization model (free vs subscription) and review sentiment (75% vs 58%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. kaizen | Adaptive Run Training sells 15 in-app purchases, starting at $12.99 per month and Lactate Training sells 2 in-app purchases, starting at $9.95 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

kaizen | Adaptive Run Training holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: kaizen | Adaptive Run Training has 29 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 58% of kaizen | Adaptive Run Training's written reviews are positive against 75% of Lactate Training's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

kaizen | Adaptive Run Training ships an update every 10 days, Lactate Training every 9 days. Both last shipped on October 24, 2026.
