Trail riding in winter is a completely different experience than in other seasons. The woods seem to be much more peaceful and quiet in winter. And the white snow makes it brighter. In fact, if the sky is clear, one of favourite things is to ride at night. And if the moon is out I almost don’t need lights.
With the snow packed in around the roots and rocks, it makes the trails nice and smooth. While I enjoy riding my mountain bike over the rougher terrain, it is a nice treat to be able to ride trails that are a lot less jarring. And I should also say that on the rare occasion that I do fall off my bike, it’s a lot softer falling in snow than on rocks.
It is winter, and you do have to dress for the weather, but as soon as you start cycling up that first hill, you will generate a lot of heat. My hands and feet will get chilly if I don’t wear warm mittens and footwear but I rarely have any problems keeping the rest of me warm.
