The AI training assistant for runners and busy coaches.

KULG is launching KULG Run Club this August with new beginner and advanced running groups. Bringing together personalised coaching, evidence-based training, and a supportive community, the club is designed to help runners of all levels train consistently, improve their performance, and enjoy the journey, whether in Tallinn or remotely.

Since joining the Tehnopol Zebra scale-up programme in 2025, KULG has benefited from mentorship, hands-on growth workshops, and the opportunity to showcase the company at major Estonian tech events such as Startup Day and Latitude59.

KULG has launched a new way to share training progress on socials, available on KULG iOS app. Turn weeks, months, or even a full year of training into a shareable visual recap of your progress. Download pie, line, or bar charts across 20+ activity types with white, black, or transparent backgrounds, and easily overlay them on your own images for sharing.

Most runners experience an injury at some point in their lifetime, and chances are, you’re at risk as well. They are common among both elite and beginner runners. But you can break the cycle and make choices that meaningfully reduce the risk of recurring injury.e. Here are 6 tips on how to prevent running injuries

In the latest issue of Jooksja magazine, KULG founder and CEO Maris Heinaru reflects on her 28th marathon and the lessons learned from an ambitious training experiment. She reflects on how rapidly increased training stress can impact the body. The article offers a real-world example of why data must always be interpreted in context and why early warning signs should not be ignored.

With its latest release, KULG introduces a major upgrade to how runners understand and improve their training: KULG AI Training Assistant, the first fully context-aware personal coaching system that knows the athlete’s training history, performance patterns, recovery signals, and goals. Instead of generic training advice, runners get instant, evidence-based insights and guidance tailored to their unique physiology and context.

Cyclical sports are known for placing mechanical load on the same tissues over and over again, which is why overuse injuries are so common in these activities. In long-distance running, it’s the lower extremities that need to bear and absorb most of the stress, and consequently, the legs are the most commonly injured part of the runner’s body. These are the most common running-related overuse injuries among runners.

On May 27, KULG is hosting the “Data-Driven Running” workshop for running coaches and athletes, exploring how a data-driven and analytical approach can support training planning and athlete development, aligned with KULG’s mission to make scientific coaching more accessible and transparent.

In collaboration with SA Liikumisharrastuse kompetentsikeskus (Liigume.ee), we’re hosting a free online session on how movement coaches can use KULG to better support their clients in planning, monitoring, and understanding training. The workshop will be held in Estonian on May 14.

Workouts alone don’t explain performance. Two runners with identical training load and experience can do the same session and respond completely differently. We want to help recreational athletes understand how to consider their physiology and context when making their next training decision. That’s why we’ve just added a new Athlete profile for runners in KULG.
