A simple eco-friendly rule that I embrace is to do what is best for the season.  This applies to the type of exercise you engage in, the foods you eat, the activities you do, etc.  For example, in the fall, we love making pumpkin based recipes with hearty fall vegetables (think squash and sweet potatoes).  In terms of exercise, it's the best time to go bicycle riding and running outdoors before the cold weather sets in.


I have been trying to alternate between running and biking during the week. Am hoping to compete in another race before the end of the year.  


Just another purchasing tip, if you are in the market for buying a new bike, look out for end of the year close out models in the fall or spring season.  Also, make sure you sign up for the free email alerts from your local bike shop so you get an opportunity to browse and purchase the goods (usually in a pre-season sale) before the general public.
