The plan was to ride from Tso Moriri to Tso Kar and then join the Manali highway at Debring. The road was pretty rough, and we got a bit disoriented by the time we got to Debring, and Me and Delzad ended up riding the wrong way! Back to Leh! We went all the way to Tanglang La before we realised we were going the opposite direction! 
I am never coming down! I don't want to go back home! 
We crossed the Gata loops in darkness, pursued by a malevolent truck who had decided to come down the whole descent without his engine on! He scared the pants off us! 
Finally we stayed the night in a little tent dorm at Sarchu and crossed Baralacha pass and Rohtang pass to Manali the next day
