@Shadrach, I had a cheap tarp over part of my run. The tarp lasted about 9 months; better than I thought it would. It broke down in the sun and you could see tiny holes in it.
I replaced it with a black/silver tarp, probably similar to the one you linked to. I've used that kind of tarp before over a different part of the run, and it held up VERY well. (It's covering a woodpile now.) I'm thinking this new one will last 2-3 years, easily.
It also has about twice as many grommet holes as the cheap one, so it can be tied down more securely.
