Sofie Deblieck + 5000m | KilimanjaroKortenaken
5/517-10-2016No problems with altitude sickness! The feeling of general fitness has increased considerably. Clearly noticeable (positive) difference with regard to physical preparedness during exercise. Energetic feeling after the hypoxic training with the mask. It goes without saying that I am a fan of your good service. Thanks for the guidance during our preparation.
