It really isn’t a problem. You can walk at your own pace nearly all the time, as we have enough guides to escort walkers of all speeds. Occasionally for safety reasons the trek leader might pull the group together (eg. in bad weather or on a tricky section of the trek route like ascending and descending Auden’s Col, Crossing crevasses over Khatling glacier, Crossing the makeshift bridge over Bhilangana river, and climbing up to the Mayali pas. In general, the group can string out and everyone finds their own comfortable walking pace.
