Autumn race season means peak training weeks and peak injury risk. In the first episode of the Sportland x KULG series, Olympic marathoner Roman Fosti and KULG founder Maris Heinaru talk through how to plan training load, avoid overtraining, and build a block that actually gets you to the start line healthy.

TalTech's science publication Trialoog featured KULG, exploring how our AI combines scientific research with personal training, health, and recovery data.

e-Residency just published a guide on how to invest in Estonian startups — and it tells a story close to home for us: how Philip Hogg, a runner and e-resident business angel from the UK, found his way to KULG.

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.

KULG is one of the 15 selected startups from Sweden, Finland, and Estonia in the GSAI (Growth and Scaling through AI) programme. GSAI is a 9-month international growth programme that helps startups strategically integrate AI into their business operations and prepare for expansion into new markets.

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.

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.

Something has bothered me for years in sports tech: we treat the human body like a collection of separate dashboards. Heart rate, sleep quality, GPS, stress scores. Each metric lives in its own silo, reported as if it operates independently. But here's what we know from physiology and what every athlete intuitively feels: Everything is connected. Every cell, every mitochondrion, every nerve.

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.

Spring marathons test your endurance, strategy and recovery. But how can you push your limits without overdoing it? Find out how to plan your training, time your peak performance, and use tools like KULG App to stay on track.

In April, KULG launched a new campaign: Are you winning in the long run? Most fitness apps are built around performance - pushing users to improve, go faster, and train harder. But in sport, improvement almost always means increasing training load. And that’s only one side of the equation. The other? Recovery. A more aggressive plan might boost fitness in the short term, but will it keep a runner training consistently in the weeks, months, and years to come?

We are proud to collaborate with Rapla Selveri Suurjooks, supporting runners in training more consciously and achieving their goals in a sustainable way. As part of the race partnership, all KULG runners receive 25% off registration for any distance at Rapla Selveri Suurjooks. Get the race promo code in KULG App and use it when registering for any race distance until May 10.

Good runners don’t just run. They cycle. They swim. They strength train. They build resilience by training beyond just running. That’s why we’ve just launched multi-sport graphs in KULG. Different sports can now be viewed directly on KULG Dashboard, providing a clear picture of overall training load beyond just running.

Each year, around 50% of runners report an injury, and an even greater proportion experience a running-related injury at some point in their lives. In many cases, these injuries are not caused by a single event, but develop gradually due to repeated overload of muscles, tendons, and bones.
