I walk anywhere from 5-7 days a week, and usually log somewhere up around 800 km of walking each year. I've been doing that for about 8 years, and maybe about half that for many years before.
These days, my walks are usually at lunch, although I/we will go for evening walks now and then too. Our favourite evening route is down to the beach, and then along the packed sand for the length of the beach and back. I often go barefoot for that, and it seems to ease my arthritis.
We also walk/run on the treadmill at the gym and are looking into getting a treadmill of our own.
And we hike ... there are heaps of hiking trails around here, so we do all or part of one every now and then.
