This tour is quite challenging and you need to be in very good physical condition to attempt it but it is a fantastic objective for the emerging high altitude expedition climbers. You will spend 8 days on your feet, trekking and traversing complex glaciated terrain at very high altitudes. The tour also includes two physically draining 8+ hour expedition-style summit attempts with alpine starts. To ensure you have a fun and safe tour, you should make sure that your cardio, physical strength, and uphill endurance are up to par.
I would follow Sunny anywhere! She is a strong, intelligent leader with a realistic understanding of the circumstances and limitations of the group in the moment and over the course of the expedition. Before the expedition, she set forth some expectations of ability with training milestones to meet to be set up for success. During the expedition, she will encourage and push for your own inner strength to shine through but will also suggest a descent if needed. That is why I’d follow her anywhere – I trust her level of awareness and knack for safety!!
