Good going. My commute is 10-12 miles each way, but will increase to about 15 miles next spring when we move to a new office. Red lights are definitely an average speed killer. Today I caught every single red light on my route, but that was OK because I was taking it easy due to the heat and humidity. My goal is to bike commute every day, but realistically it usually works out to 3-4 days/week depending on the weather, work schedule and errands.
