The High Passes of Everest trek was the first trip of this kind that I have done and was my 50th birthday treat to myself. Although I had never experienced altitude before, and had limited walking experience, I felt that I was fit enough and determined enough to take on the challenge of what is described as a 'tough' trek. Our guides stressed the need for a steady pace in order for us to acclimatise properly and be able to cope with many hard days spent at over 5000m. I never felt any of the symptoms of altitude sickness due mainly, I believe, to proper hydration. Along with the other 14 in the group (average age 51.9), I made base camp. Only 6 of us (ave. age 56.8) managed all 5 peaks and 3 passes, so I am justly proud of accomplishing that! The main reason that so few of the group managed all peaks and passes was down to illness, although 2 in the group weren't really fit enough and seemed to want to use the trek as a weight-loss exercise! I also went to Chitwan for 2 nights at the end of the trek. This was a thoroughly relaxing way to end my holiday.
