CYCLING IN THE RAIN
Stay warm. Time to get those arm/leg warmers out of the closet (or buy some if they're not part of your wardrobe yet). Gloves, shoe covers, and rain jackets are also very worthy investments. Dress in layers so that you won't broil climbing Snake Hill or freeze going down Centre Street. Remember, if you wear 2 jerseys, you'll have 6 pockets!
Stay dry. Fenders are a good idea. Neoprene clothing also keeps you quite dry. Goretex is great, if you can afford it. Those plastic bags are a cheap/good way to keep your feet dry.
