Chain problems

Tusayan to ash fork Az 75. Today was the first time in a while where I didn't have any major climbs. Last night I decided it would be a good day to go for another century. I headed out after doing the double breakfast. First I made oatmeal then went to MacDonald for a breakfast sandwich. I was feeling good and making good time. Then about 20 mi in the trouble started. I was pedaling up a small hill and then out of know where no tension and my legs were spinning like crazy. I look back and my chain is laying on the road ten feat back. I ran to get it and then sat on the side of the road and fixed it. After taking out the bad link I rethreaded chain and put it back together. When I reconnected it I bent a piece of the link. U wasn't about to take that link off so I said hell with it and started riding hoping  it would hold. Once I started riding it was very apparent that something was wrong there was a loud rubbing noise. I figured it was just the bent link rubbing on something. I eventually realized that the noise wasn't the bent link it was because I had messed up threading the chain. The way I had threaded it, it was causing the chain to rub. I had to unconnect the chain and rethread it. This chain was pissing  me off and I was praying that they would have a replacement at the bike store  40 mi away. I was also hoping the cain would make it that far. It made it 35. So there I was again sitting on the side of the road taking another link out. I road the last five miles to the bike store not doing much shifting not wanting to stress chain. The bike store want really a bike store. It was a Coffey store with bike repairs in the back. I was really hoping they would have what I needed. They had 3 chains and luckily one would work for me. My rear cog was also warn out and some how this guy had all those parts that would work as well. I got really lucky. With all of these delays there was no way the century was going to happen. After the bike store it was 17 mi to the next town and most of it was down hill. I banged out these last miles and called it a day. My bike is running the best it has all trip. The guy who helped me is pictured below.
