I currently run standard marathons on my touring bike, which also sees a great deal of commuting time. I put them on just over a year and a half ago, after getting numerous flats in a short period of time with another tire.

They certainly aren’t the lightest tire out there, but they roll reasonably well and I’ve had zero flats so far. When they wear out, I see no reason to switch to anything else for this bike.

I should note that I don’t know how many miles I’ve got on them as I switch up my ride periodically, but I’m very happy with their performance so far.
