We bike fit, we train,
and organize camps for cyclists and triathletes
KOA means brave, courageous in Hawaiian. And that's what we think anyone who decides to take on the adventure of endurance sports is.
We are constantly working on ourselves so that you can work on yourself according to the latest findings. We follow trends and actively engage the meaningful ones in the gym and in the fitting room. Because stagnation is worse than training deficiency.

Bike Fitting
Don't settle for less, let the best set your driving position. We've been doing bike fitting and sizing on a daily basis for over 15 years, working with Velogicfit, gebioMized and Aerocoach technologies.

Training
Triathlon, running, swimming, cycling, fitness training in the gym and restorative yoga. We'll prepare a long term online training plan tailored to you and we'd love to see you in guided sessions at the Gym.

Camps
Every year we go with an accompanying vehicle to one triathlon camp and several cycling camps in the Czech Republic and abroad. Performance groups, trail rides and experienced guides are a matter of course.

We started triathlon after we finished our studies at FTVS, but we did it properly. Through participating in the Xterra World Championships in Maui and Ironman in Hawaii, we got to train our own charges. We founded the KOA Endurance Studio in Letna in 2018, a little while after Honza returned from his head coaching mission in Hong Kong, where he also started doing bike fitting. A field in which he has developed into a real world leader.
Welcome to KOA
Do you always want to be ready for any physical activity? Leave us an email and we'll give you access to the KOA plan with dynamic stretching. And as a bonus, we'll send you our newsletter the first Wednesday of the month.
We are based in Letná, Prague, but we also train in Japan.
Bike fitting, guided workouts in the gym, restorative yoga and a party here and there. It all happens at our studio in Jirečkova 7.

We can't wait:
