Real riders. Real results.

I started training with Kosta about a year ago, and it's been a game changer. I didn't have much cycling experience as I had just started training on Zwift, and wanted to get better at Zwift racing. With Kosta's training, my Zwift racing score went from 145 to almost 300 in 6 months and was getting on the podium in C division.

My cycling journey has transformed, with my FTP increasing from 160 to 255 watts. Kosta's dedication to my progress, weekly check-ins, and personalized plans have made a world of difference. I would highly recommend to anyone who is looking for a coach. He's the man!

Working with Kosta has been a game-changer for my cycling. His structured training plans gave me the focus and consistency I needed—not only did I increase my FTP, but I also achieved one of my biggest goals: winning a Zwift Racing League race.

Kosta guided me to become the best version of myself on the bike. He delivered everything he promised and often went above and beyond. I can't recommend him highly enough—if you're serious about improving, Kosta is the coach you want in your corner.

Going into my first season of racing in the women's Bundesliga this year, I was looking for support not just for developing my power, but also for racing strategies, positioning and tactics, nutrition, and recovery.

I have really appreciated the high level of personalised support that Kostiantyn provides. I am super excited for the next season!

When I started working with Kosta, my main goal was to build the strength and endurance to take on long, challenging races like a Gran Fondo. Kosta changed everything. His structured plans gave me clarity and purpose.

Over time, my FTP jumped by more than 40 watts, and I became smarter with how I train, race, and recover. One of my proudest moments was riding the Gran Fondo in Austria in 2025. I feel fitter, faster, and more confident than ever on the bike.
