If you buy some 'one way' walking sticks, you can walk a lot further distance.
Carbon fibre, adjustable with wrist straps to take some of the strain.
Called Nordic walking poles and they have a Web site and, if you are interested you can join Nordic walking groups all round the world.
Reported that you burn 2x Calories using walking poles. Gives you a whole body work out as arms as well as legs used.
Nordic have developed a special walking style. Takes a bit to master.
I'm 78 and been using them for years as have lumbar nerve damage and knee replacements.
Have a go.:)
Buy me a beer when you see me.
