1 - The "3 layer" system for the fast walker in winter
Do you really feel the cold during the winter? Does your motivation take a nose-dive when the cold weather hits?
The solution is to put on 3 warm layers. These successive layers of insulation protect you from the cold, and enable you to adjust your thermal protection as the effort requires. Although you may feel cold on starting, the exertion will quickly warm you up, and you'll start to sweat after a few kilometres of fitness walking. It is therefore important to be able to remove and add layers of thermal protection according to your needs.
The 3-layer system is recommended by cross-country walker Emmanuel Lassalle, who's spent long hours training, in all weathers:
"On top, I wear a "first layer" vest, to keep the heat in. On top of that I wear a long-sleeved zipped top to insulate me from the cold. Then I wear a waterproof and breathable jacket to protect me from the wind and bad weather."
N.B.: avoid cotton clothing that gets wet when you sweat and go for breathable fabrics. For easy removal of layers as you walk, choose clothing with zips!
