Wintertime Riding
Winter riding can be fun. We just need to keep a couple of things in mind; it can be cold and it can be wet. We just need to plan and dress accordingly.
First, pay attention to the weather. Generally you will have some forewarning before you get a big winter storm. I suggest altering your training so that when it starts raining you can take a day off, then if you must go ride outdoors. Otherwise you can stay indoors and ride the trainer or take a bit more rest.
Second, if you live somewhere that it rains a lot put a set of fenders on your bike. The fenders really cut down the amount of road grit and water that gets thrown up when it rains. I have found with a little craftiness you can attach full fenders to nearly any bike.
Third, dress warmly and in layers. First is the base layer, for which I suggest lightweight polypropylene. This will wick away the moisture and gives you a nice insulation layer. Second, put on a warm layer, such as a long sleeve jersey. This is usually fine if the temperature is in the upper 50’s or low 60’s. However, if it is colder (40’s and below) you will want something like a semi breathable jacket such as Windex (gore) or maybe even a more waterproof, e.g. Gore-Tex (gore) jacket. Lastly, always carry a lightweight jacket that is both water and windproof or at a minimum a vest. It will keep you from getting chilled if you stop riding or descend.
Furthermore, make sure to keep your head warm because you lose 25% of your heat through your head. There are many thin polypropylene and Windex hats and headbands to choose from that will fit underneath your helmet. I recommend leg warmers as opposed to tights because you can use them for multiple days before washing; I own several pairs so I can rotate them through the wash. If it is cold use the furry lined leggings, which build up a toasty insulation layer and not lycra ones. Also in cold climates you might want furry lined shorts to go with the leg warmers. Additionally, wear booties or toe warmers to keep your feet warm.
In colder climates you can put heating packets between your booties and shoes to keep your feet warm. When it’s wet out I also recommend carrying a second pair of gloves. Keep them under your rain jacket and pull them out half way through the ride. Your hands will warm up, and you’ll be much happier. When the roads get wet, they and your brakes can get mighty slick. Take it easy through turns, watch out for metal grates and leaves, and apply your brakes well before you need to stop - this will clean the water off your rims so your brakes will work properly. Also, make sure to have fun and stay healthy during these wet winter months.
