i think i will start hiking, it typically involves virgorous walking, usually on trials, in the countryside
I love hiking.  It really helps with physical and mental health
yea and worldwide the term walking is acceptable to describe all forms of walking, wether it is a walk in the park or backpacking which is strange
Do you know when hiking first became popular as a sport?
well if you go all the way back to 1927, they first started what was called bushwalking in ausstralia 
I can see hiking being a big thing in the land down under.  Lots of land to roam
yea well it is popular with numerous people worldwide, and studies suggest that all forms of walking have health benefits.
