To keep our mountain and nature clean, we will not be providing single use plastic cups and small (500 ml) water bottles at the aid stations. Every racer should carry their own bottle and cup. Please carry all used food packages and other rubbish with you and discard them at the aid stations. Thanks to Bulecopack and “За Земята” NGO, our aid stations will be equipped with designated bins for recyclables (plastic and aluminum).
