Having been a Nordic Walking instructor for two and half years, I am please say that although I take my walkers on all terrains in all sorts of weather, I have never had an injury or fall. I strongly believe that this is because everyone has poles. Not only are they great way to work the whole body, they provide the vital support on wet, rough and slippy ground. I would never take a walking group in the countryside without them. Come and give it a try.
