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.

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.

Already this Saturday, April 11, runners will gather for the traditional Haapsalu run - one of the most anticipated early-season running events with a fast and flat 10 km race. All participants of the Haapsalu run will receive 3 months of KULG Runner for free.

We’ve just rolled out a number of exciting updates that help save the time of busy coaches and make athlete management simpler and faster - training blocks for season planning, athlete dashboard, and copying weekly group plans.

What if you could predict your athletes' injury risk before it happens - and adjust training in real time to prevent it? That's not science fiction anymore. The latest research shows AI-powered systems are now analysing multidimensional athlete data to predict optimal training loads with unprecedented accuracy.

We’ve introduced a new Aerobic fitness score in KULG App to help runners better understand their endurance development. This makes it easier for runners to track their running progress, monitor adaptations, and understand changes in aerobic fitness.

You have more data than any runner in history. But data without understanding won't make you a better runner. KULG is about zooming out, finding patterns, and making sense of your training over time, rather than focusing on each individual session.

Martin brings deep expertise in AI and product development as well as strong ideas about how we can take the next step in our product, especially around adaptive, AI-powered training planning for runners and coaches, which aligns closely with where we see the future of KULG. As we continue to build tools for coaches, clubs, and runners, AI will play an increasingly central role in the product.

Introducing a brand-new feature for coaches on the Coach plan: Planner. Planner is designed to save time, streamline communication, and make planning more efficient for both coaches and athletes. Planner allows coaches or club admins to plan a full training week for multiple athletes and send it directly to their KULG app calendar.

We’ve launched KULG Android app, joining our iOS app as a companion experience to our web platform. Runners and running coaches can now access core training insights and stay connected to their training and recovery across different devices in most countries worldwide.

One of the reasons we built KULG was to give runners a simple, focused view of their training and recovery with clear insights on how to improve. That’s why we just launched a new weekly Overview for runners. It brings the training adaptation and readiness indicators that actually matter into one place.
