Toilet booths are placed along the marathon track, half marathon and 10 km routes.
At the Radenska Light Half Marathon, they can be found in two places, and at Radenska Classic Marathon at four. At the Radenska Naturelle run (10 km), the toilet booths are arranged in one place.
In the start-finish area, toilet booths will be available in the immediate vicinity of the finish line.

Showers will be set up with the help of the Slovenian Armed Forces in the start-finish area as well.
