What a day. Stayed in Potosi Bolivia last night and we were up bright and early to make tracks for Oruro. We looked forward to arriving at a reasonable time to allow us a chance to check the bikes and catch up with our social media. It was our usual chaos getting out of town with no sat nav reception but after half an hour we were on our way (or so we thought). About 3 miles out of town I could not avoid a rock that came rolling onto the road in front of me and the result was a front tyre blow out. I knew straight away as my front end went light and wobbly. I pulled over to the side of the road and was gutted to see it was gashed beyond repair. There was nothing for it but have Wilson and Raymond head back into town to look for someone to pick up the bike. They were gone for a while and during that time I had a couple of locals stop to check on me. Just before the lads arrived back Andrew the Canadian we had met a few days ago pulled over. He could not help but advised me we had been heading in completely the wrong direction. Wilson and Raymond came back and told me that they had found a mechanic who would repair (no chance) or replace the tyre but we needed to bring it in. So it was out with the tools including rocks to prop Boris up and off with the wheel. The guys headed back into town while I waited doing some nuts and bolt checks and reflecting on life. Another biker Peter from South Africa pulled up and chatted to me. His wife had died and his kids were grown up so he had decided to ride the Americas for a year. Another great human encounter. Soon after the rescue team arrived with my new tyre which they described as a rally chopper tyre. They weren't far wrong, not quite the right size, tubed instead of tubeless, off-road orientated and £40 fitted. The wheel fitting process was painless after which we agreed, as we had lost most of the day, to go back to last nights hostel in Potosi.The ride back on the new tyre was interesting. For sure I will be keeping my speed in check until we can find a proper replacement. Maybe in Peru? My thanks to my two amigos for their help and support today.
