Note: Employees of Utrecht University, UMC Utrecht and Olympos can sign up for free (up to a certain maximum number of participants). Please check your own organisation's Intranet or other internal communication channels for further information.
Running practice (free for OlymPas holders)
Want to arrive at the start of the race well prepared and set a fast time? Sign up for one of Olympos' running practices. You can choose from practice for beginners, for the 5-10 km distances or for the 10+ km (half/half marathon) races. Participation (registration) is free for OlymPas holders.
Once-a-week practice sessions under the guidance of a professional instructor will ensure that you progress quickly and responsibly, improve your technique, and push your limits. The instructor will provide you with weekly feedback. Furthermore, running in a group is very motivating as well as fun! You will be running in the beautiful rural surroundings of the Utrecht Science Park.
10-week sessions
The running practices are scheduled in consecutive periods of 10 weeks/lessons. You must, however, reregister for a next period of 10 weeks to give other athletes a chance to participate too. You can register and participate at any time, even after the practice period has already started. When signing up, your OlymPas must be valid until at least the end of the current practice period. You can choose a monthly OlymPas or an annual one (this latter one is relatively inexpensive).
