@kevinmaveric: Everyone has his/her own metabolism, you yourself say you've suffered twice and last year you didnt
Paagal nullah is 4 kms before Pangong, and is should be crossed by 2 unless you plan on staying there. Having said that pangong is doable in a one day. The key is time your ride well, leave early. I did it in a day last year.
But cross changla by 5-5:30 lest you'll be stopped near the check post before chang-la
@groupbhp: No alternative route was being made, of all I saw.
