So on a Typical Day

5-10km when it's not winter time.
0-5km in winter time.

I don't use the car for farming stops and mons. I also don't use it for increasing km.

Summer/early fall:
On a typical day though I would generally average 3-4km. If I was going on a run that day, add in an average of 6km.

Winter:
Through driving, about 2km. If i'm walking my dogs, add an extra 2km (4km total).

Have dog, prob 5-7km/day. Usually just hit stops on my work route/errands so not too hard to keep stocked...I've noticed it's also easier to have enough balls if I don't hoard revives, berries...Just keep the minimum (40 or so of each). I lack enough defenders to worry about running out of revives daily too so no problems there.

Usually don't need to drive, but will if I need to do a few loops to restock if family goes to special place for pokemon (beach areas).

hot summer days : 5km
winter : 10 to 12km

It's my daily exercise; therefore, only walk, never drive

15km/day, give or take during the week. I walk a ton at my job, and leave my screen on my phone at work to capitalize. Weekends, significantly less, probably 5km/day.

I do farm stops and Gyms with the car, but ends up a 20 minute or less job daily. Mons I catch what I catch while walking, unless I drive to a nest with 10+ mons sitting there, which I only know of a few.

Never go by car. Since I started I have walked on average 8.5km(day. Last two months much more, 15-20km/day, with tops during events at 35km.
Long spells of freezing temperature since mid October. Worst weather in my opinion: hard wind, mixed sleet and rain and slippery icy surface.

5-8km on a working day whatever the weather.

Weekends vary.

Never felt the need to drive.
