Heading for OBT Oslo Bergen Trail 500K in 2027, Sylwia Kaczmarek has been training with Arduua for many years, building her strength, endurance and experience through consistent long-term coaching.

“I am happy and grateful that my running adventure continues under the guidance of Arduua. I find joy in pushing myself to become better and stronger.”

Her journey started with Arduua Coach Fernando Armisén, who guided her training for several years through races, ambitious goals and setbacks. Now a new chapter begins as Sylwia continues her journey with Arduua Head Coach David Garcia.

The next big challenge is already on the horizon: Oslo Bergen Trail 500K next season in 2027 — an enormous ultra-endurance adventure that will require long-term preparation, consistency and smart training.

Sylwia’s journey is a great example of what long-term coaching is about: not just preparing for one race, but developing year after year, adapting through different phases of life and training, and continuing to set new goals.
