    Course Concept

    The Croatian peninsula Istria is regarded as a dream destination for road cyclists worldwide. For Istria300 we have selected the most beautiful roads and courses and combined them into a unique road bike event. This ensures a cycling experience of a lifetime in the middle of a breathtaking landscape.

    Ride your Limits!

    The start for all participants will take place in Poreč. You can decide which distance you want to ride directly on the course. When submitting your registration, you do not have to indicate your desired course.

    Note: Due to unavoidable circumstances, the courses may be modified annually and, therefore, can be shorter or longer than the original. Especially the Istria155 can be affected by +/-9%. Nevertheless, the name of the courses “Istria155, Istria235 and Istria300” remain the same and will not be adapted annually to the current distance. The highest priority is to reach 300 Kilometers on the longest course.
