The combination of cold temperatures and limited sunlight make winter riding and running a challenging commitment to make, but it is possible to have fun outside in the winter. Over the past week I have ridden 3 times in under 20 degree weather and rode one 6 hour mountain bike ride in the snow. With proper clothing I was never uncomfortable and none of my extremities went numb. The key to my winter riding is making sure I have convertible clothing that allows me to always stay warm and dry this means regulating temperature to prevent sweat and also blocking outside moisture.
The secret that any avid winter outdoors man will tell you is to dress in layers. I typically have a base layer that wicks sweat, a thermal layer for warmth, and a wind/water layer such as a vest or wind breaker that I can take on and off depending on air flow and moisture. In addition, I use a lot of accessories that I can take on and off such as a buff, an under helmet wool skull cap and glove/shoe covers to regulate temperature.
Dressing appropriately for the weather is the easiest way to get outside when most people aren't. In the winter a lot of plants die back making for stunning views and wide trails that aren't overgrown.
