Petra bottomed out her bike on a railway track approaching the bridge out of town, and told me over the radio that her bike had stalled and wouldn't restart. I could see her in my mirrors stuck in the middle of the road with trucks and buses now weaving left and right around her, so I stopped quickly on the side of the road and ran back to walk her bike out of traffic.
I suspected the side stand kill switch had been damaged by the railway track; it's a safety feature built into the sidestand intended to ensure people don't ride away with the stand extended. I was preparing to dismantle the switch when Petra pointed out that the connecting wires may have been pinched by the frame. Sure enough, that was the problem, so after a quick splice and taping we were riding again in 15 minutes.
10 minutes outside of town we approached a number of stopped trucks on the road. Passing them slowly, we realized the road ahead was closed. It had rained heavily in the night to the north of Tupiza, and presumably this had caused a rock slide, blocking a section of road some 200 feet above our road. A heavy equipment crew was clearing that slide by pushing the rock and debris down onto our road, from where they would then push it over into the canyon beneath us.
Last nights rain, together with the fact that the vast majority of Bolivian vehicles using these roads are trucks or buses, meant the poor quality desvio had taken a beating. We rode for hours on incredibly challenging terrain - washed out roads, deep puddles, and 500m long stretches of deeply rutted thick mud.

I fell sideways in a deep slippery rut, but only slightly as the side of the rut was high enough to hold the bike upright. Petra had a bigger fall as her bike bounced off one side of a rut and ran up and over the opposite side.

The road improved from that point as we continued north, only to find after 5 hours of riding that we had gotten onto the wrong path somehow, and were headed to Potosi not Uyuni. If I had an eject button, I might have used it at that moment!
Potosi is the highest elevated city in the world at over 13,300 feet above sea level. It is an old colonial city with narrow streets, cobbled and steep, set into the slopes of the adjacent mountains. There are virtually no traffic signs, signals or markings. The traffic is chaotic.
We struggled to find a hotel before dark, and put up for the night dejected at the thought of another long ride to our intended destination of Uyuni tomorrow.
