  • Kaizen has been a game-changer for my running! Its race time predictions from 5km to marathon distances were spot-on, giving me confidence in my goals. The ability to train using the app’s training load feature has been invaluable, helping me improve my fitness while avoiding injuries. Highly recommend it to runners of all levels!!

  • Kaizen hovered around 2:51 a week out from marathon, came in at 2:54:42 on a very windy day on quite hilly course so allowing for that I think prediction quite close and will use again for next one. Cheers!

  • Kaizen team - I just want to thank you all for a fantastic job. I ran CIM yesterday at almost the exact prediction from the app, 1:39 under to be exact, which checks out considering the net loss of elevation. The confidence I will have going into my next race will be in large part to the trust in the work you all are doing here. Keep it up. Amazing work

  • Followed the app for my 16 week block on the road to the Amsterdam Marathon with a set goal of a 4hr 11min marathon, I successfully achieved well in advance of it with a 3hr 41min result. Absolutely delighted with it! Kaizen helped greatly in getting me in the groove and fitness to smash it!

  • This app has surprisingly become my go-to and main driver of training load to gauge and improve fitness gradually.

36:10 10km

  • Currently, you can train for 5k, 10k, half marathon and marathon races using Kaizen. In the future, Kaizen will be able to support custom distances from 3k to 50k.

  • No, kaizen is built around guiding the right amount of work, not forcing everyone into the same rigid session-by-session plan.

  • The most important thing is to be consistent, so your training should be in service of that need for consistency.

  • It means the realistic upper end of what your current training could support under strong race-day conditions and good execution.
