Little time and a quick MTB training to do? This proposal is ideal for a quick training with several hills. The purpose of our trip is the Zielona Góra Reserve, where you can spend more time if you can want ride on more difficult sections. Then you go up the Ossona Mountain and Kamieniołom. The loop in this form should not cause any problems, but should not be underestimated. It contains several more difficult elements and harder uphills.
