ATTQOTD: Mostly asphalt (mainly when on roads, but once in a while on sidewalks, there are asphalt sidewalks in some places), followed by concrete sidewalks (they don't do roads in concrete up here), then maybe a little bit of dirt, followed by a miniscule amount of brick/cobblestone.
I greatly prefer asphalt, but there's also 2 different kinds of concrete sidewalks and one I prefer over the other if we're running on sidewalks. Anywhere there are brand new poured sidewalks, the kind where the concrete is poured there, or like most of the sidewalks I would encounter at my parents when I visited them in FL... those kind I hate. We also have a lot of older, lumpier, more uneven concrete sidewalks around here that I think are concrete slabs that were placed on the ground after they were hard. They're thinner and things like tree roots and what not lift them up. Anyway... I much prefer those older ones even though they're lumpier. I can absolutely feel the difference between them and the newer kind make my lower back hurt.
The brick/cobblestone can be ok to run on, although some of the cobblestone is really ooooold and uneven and you need to watch your footing so you don't twist an ankle on an uneven brick. The newer cobblestone that is nice and even... fine to run on in warmer months, but a complete hazard to run on if there's any kind of moisture in the air and it's anywhere near freezing. They get SO slippery and since the bricks are still smooth and the seams between the bricks are still perfect, running on them is like trying to run on a skating rink. I will run out in the road in that weather instead... I'd rather run on the uneven historic ones in that weather.
Edit: I guess I didn't count treadmill, which is right now all of it.

OTF has these nice squishy Freemotion treadmills that are like running on marshmellows and I'm going to be sad to go back outside to real earth, although I will also be happy because I can only stomach treadmill running in an environment like an OTF class. I cannot stand it when I'm just running to run.
