How Josh Sambrook Cut His Marathon From 3:24 to 2:28 With a System That Breaks Every Rule in Running

Most training apps tell you exactly what to do every day. Josh Sambrook helped to build one that tells you your weekly target, and lets you train however your life demands.

It’s the system that helped him run 120-mile weeks, cut his marathon time to 2:28 by age 23 (he ran his first marathon at 17), and reinvent how thousands of runners train.

Josh and Michael Keskerides are the co-founders of the Kaizen app for runners. The app is a flexible and dynamic training system that sets a training load target at the start of the week, and then the user is free to achieve this goal through whatever combination of runs works best for their lifestyle. 

With the app and this training system, athletes can “trade” intensity for distance. Kaizen is the Japanese business principle of continuous improvement; discrete, ongoing, small changes can lead to significant benefits, and they used this as their model. 

The two co-founders host the Miles Better Podcast, where they discuss running and how they use the app for training.

Josh himself is a sports scientist, builder of training systems and prediction engines, a running coach, writer, and podcaster–and he’s here to bring clarity to a sport drowning in noise.
