“Today is not the end — I can last one more day”

Adrian Kostera

I coach people whose lives don't look like a pro athlete's

My name is Adrian Kostera. I'm a running and triathlon coach and an ultra-endurance athlete — someone who tests on himself where the limit really lies.

Kostera Method is training that lives with you: work, family, short nights, shifting schedules. The plan keeps up with your life, not the other way round.

“Today is not the end — I can last one more day”
