I really want to go for a long bike ride. But so far I haven't been able to find a good road bike to rent in Warsaw. So what should I do? Go for a really long walk! I wandered around Warsaw and walked 10 miles today.
Walking isn't really strenuous, but there's something about it that takes us back to our roots as humans. Before roads, cars, and bikes, people got around by walking. And before farming, people had to move to wherever the food was. And that involved lots of walking.
I know people that have lost a lot of weight by doing nothing more than cutting junk food from their diets and going for 2 to 3 mile walks every day.
So get out there and walk. The other cool thing about walking is that you never know what you might discover.
