Only carry what you know you will use, waterproofs, gloves, hat and some food.
Most of us own so much kit over the years, that we feel we need to take everything with us on a walk.
The more you carry the heavier the weight, and more weight will slow you down and make you feel tired sooner than later.
Its tricky to balance what to take with you and what to leave at home.
I dislike extra weight for the sake of it, so carry the basic waterproofs, hat and gloves, which all way under 1Kg.
Next time you go out walking, really ask yourself do I need to take that with me, if not leave it at home.
