There was a company that did mountain biking from Muktinath to Beni a couple of years ago – So certainly no problems on the kali Gandaki side of AC and the jeep road is ever progressing up the Marsiange valley towards Manang, so certainly no problems as far as the start goes –
The bit in-between, well I would say that for an experienced and fit person it is doable – But there will be several times when you have to carry your bike, certainly where construction work on the new jeep road is ongoing and then a few times up some rather long stone steps.
Thorung La will also be a very tough day as unless you are Super Fit then, although some of the path will be technically rideable, the altitude you are at would Really Tax your lungs – Then the first part of the descent after the summit is steep and on shale, but there is a road that is 99% unused for the last ¼ into Muktinath.
Give it a go – and Please Do pop up a posting and let us all know how you got on
