Przemek Kotulski analysing the moment of the race when his legs said "enough" 😆
Przemek is a sprinter, however he's trying to work on his lactate tolerance on the climbs, to save as much power as possible for the final sprint.
"Having live data of muscle oxygenation and lactate level is a game changer for me" -Przemek
We are proud to support you !

Confidence in the technology starts with the opportunity to test it yourself.
QLAC allows you to monitor your muscles response to effort in real time- oxygenation, metabolic response, training intensity level, and lactate data calculated by our dedicated algorithm.
As the first technology of its kind in the world, QLAC brings advanced muscle and lactate analysis directly into everyday training. Research validating the technology is available on our website: https://q-lac.pl/
Test the sensor in your own training and see what you gain.
30-day return policy. Risk-free.
See for yourself how QLAC can help you better control intensity, recovery, and progress.

What’s the secret behind smarter training?
For Dariusz, 2nd fastest person on global Wings for Life World 2026 run, it’s not just about running more, it’s about understanding the body better.
That’s why he incorporated QLAC into his training.
QLAC is a non-invasive muscle oxygenation and lactate sensor designed to help athletes see how their body responds to effort in real time. With better insight into intensity, fatigue, and recovery, training becomes more precise and performance becomes easier to optimize.
Whether you’re preparing for a race, building endurance, or looking for a smarter way to train, QLAC helps you make decisions based on data, not guesswork.
