As a firefighter, you must be physically fit! I became a runner over a year and a half ago. Meanwhile, my husband Tino got into cycling. Tino cycled the Rosarito/Ensenada Bike Tour April 2008. When the same tour became available in September...we bought me a bike (used because they are SUPER expensive). This trip was not only fun and relaxing, it really did challenge my body and mind. I rode my bike for about 52 mile and it took me 3 hours and 38 minutes to complete.
