Hi - I am seriously thinking of booking this. It would be a first trip for me alone - I have always wanted to go to Nepal. Has anyone else the wrong side of 60 been or is thinking of going? There is only 1 walk that sounds challenging but I would absolutely hate to be the weakest walker in the group and hold others back. There is only 1 review for this trip so there is no info from others as to how strenuous they found it. It would be good to hear from others who have been or are going, as to their level of walkimg ability and fitness. I just need a bit more confidence to go ahead. Thanks.
