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 hard just started training on Zwift, and wanted to get better at Zwift racing. With Kosta training, my Zwift racing score when from 145 to almost 300 in 6 months and was getting on the podium in C division.
From the moment I signed up, Kosta’s support has been next level. Whether it’s training advice, nutrition tips, or bike queries. My schedule is constantly changing with my regular life commitments, which causes lots of scheduling changing, Kosta always tailors my training no matter how many times I need to move scheduled training around!
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. It’s been one of my best decisions, and I couldn’t be happier with this incredible coaching experience. 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. He’s incredibly knowledgeable, approachable, and always brings positive energy to every session. 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, always communicating clearly and supporting me through every phase of training. 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 some serious support in helping prepare me for the races ahead. Not only in terms of developing my power on the bike, but also for discussing racing strategies, positioning and tactics, nutrition, and recovery.
It was also important for me to understand the purpose of my different sessions, their key targets and how I should fuel them, and it has been great working with a coach who very openly discusses this with me and answers any questions I have.
I have really appreciated the high level of personalised support that Kostiantyn provides, and this is something I have both seen and felt the benefits of massively in my training and performance. 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. Up until then, I was training on my own, riding a lot of kilometers but never really improving in the way I wanted.
Kosta changed everything. His structured plans gave me clarity and purpose. Every session had a reason behind it, and he always explained what we were targeting and why. Over time, my FTP jumped by more than 40 watts, but just as importantly, I became smarter with how I train, race, and recover.
One of my proudest moments was riding the Gran Fondo in Austria in 2025. It had always been on my bucket list, but I honestly never thought I could keep up with the first group at a competitive pace.
Kosta doesn’t just hand you a plan—he adapts it to your life, checks in regularly, and makes sure you’re progressing in the right direction. For me, this has been a complete transformation. I feel fitter, faster, and more confident than ever on the bike, and I can’t wait to see what’s next.
With over a decade of experience in high-performance endurance sports, I help cyclists unlock their full potential through structured, data-driven, and fully personalised coaching.
At Ventro we are aiming to understand the needs of the athelete, set your goals, adapting training to your life, and building a partnership based on trust, communication, and real progress.
Absolutely. Whether you're new to cycling or getting back into it, we create training plans that match your fitness level and goals. The focus is on gradual progression and sustainable performance gains.
Definitely. We work with competitive cyclists targeting podiums, race wins, and category upgrades. You'll get structured periodisation, detailed data analysis, and racing-specific training blocks tailored to your peak events.
We monitor key metrics like power curves, training load (CTL/ATL), fatigue management, and FTP. We use this data to fine-tune your workouts and ensure you're peaking at the right time without overtraining.
We update your plan on a weekly basis based on your progress, feedback, and data. This ensures the training remains effective, aligned with your goals, and adapts to changes in your performance or schedule.
Many cyclists notice improvements in endurance, power, or speed within the first 3–4 Weeks. More significant results typically come after consistent training over 2–3 months.
We focus on data-driven and personalized coaching. Your plan is built around your power or heart rate zones, goals, available time, and event schedule. It's not a one-size-fits-all program.
If you've been riding regularly and want to target specific performance metrics or race goals, you’re likely ready. Our coach can assess your data and tailor the plan to challenge you appropriately.
Yes. If your objectives change—like shifting focus from a gran fondo to criterium racing—we’ll adjust your plan accordingly. Flexibility is part of our coaching philosophy.
At minimum, you'll need a road bike and a cycling computer. A power meter or heart rate monitor is highly recommended for more precise training and analysis. We can help you choose the right setup for your goals and budget.
No problem. Life happens. Your coach will adjust your plan based on changes in availability or missed sessions, so you stay on track without unnecessary stress.
Not at all. We coach cyclists of all backgrounds—from complete beginners to seasoned racers. Your current level just helps us set a realistic starting point for building fitness effectively.
