Nice initiative. But don't stop there.
Some tips:
Try walks that are longer. 30 min is a warm-up. 4h trips would be a good training. Try increasing the interval gradually.
Try them in various weather conditions (in bad weather 30min ones are good too, they help you adapt and prevent many things in a real need situation).
Try different paths, test them during day, but try traveling them at night too.
Don't use any tech (except flashlight and/or laser at night). If you can do it without tech, you can do it with it too, but don't take tech for granted.
At night, against doggies of any kind, fell free to use green lasers of 100mW+. They are ultra efficient in scaring them off. Green lasers are a must. If you can get a flashlight with you, you can also get a green laser. Advantages: you can use it against various creeplings, you can use it as infinite-range flashlight (a good green will have enough range to reach Earth curvature) and you can even start a fire if it's powerful enough (if not, you can still start a fire with it's power cell).
All this aside, walking (anywhere anytime) helps. A daily walk (but fast pace, army-like) of even 1Km can drastically improve one's overall shape and it's something that can be done at any age. Do this for a few months and you're at 90% of a very good physical shape. Give the laziness of meatbags today, most of the people are clearly unfit for many things considered usual in the past. It's up to everyone to change that.
