Oleks Sirko

Data-driven coaching. Real results. No shortcuts.

I’m Oleks — a certified cycling coach from Ukraine, but now based in Greece, working with athletes across the world. I’ve been racing as a cyclist myself, so I know exactly what it takes to build fitness around a real life, a real schedule, and real goals. My approach is simple: understand your body through data, train with purpose, and build performance that lasts. No guesswork. No cookie-cutter plans.

What makes my coaching different: Every athlete gets a full power profile after 14 days — not just an FTP number, but a clear picture of where you’re strong, where you’re limited, and exactly what to train. I use in-workout field testing instead of isolated FTP tests, because your real numbers come from real riding. I track what matters: FTP, power curve, VO2max estimate, HRV, resting HR, CTL/ATL/TSB, and sleep quality. You’ll always know where you stand and why.

Real results from real athletes: One athlete went from 225W (3.01 W/kg) to 274W (3.75 W/kg) in 10 months — a +21% FTP improvement through structured load, targeted strength work, and recovery optimization. Other athletes have won their age-category races. Progress here is measured, not promised. “Working with Oleks is easy and never boring — results come without burnout or overtraining.”

Who I work best with: Motivated athletes who value structure, honest communication, and consistency. Beginners building their first real base. Amateurs preparing for gran fondos, stage races, or their first podium. Masters riders who want to keep getting faster. I’m not for you if you’re looking for a magic fix or Olympic results in 3 months.
