Today is day 5. I've ridden every day except yesterday. I was worn out from work (which is also physically demanding). I was feeling guilty for not riding, so I climbed on my health rider for a little while, just to keep up the exercise habit. Today I only rode 2.4 miles. Yesterday none. And the day before I only did 1.5 simply because my six-year-old son wished to join me. And it was raining. But, I've been told it only takes two weeks to make or break a habit. So I'm going to keep at it! Besides, it's so much fun. I've found a group that I'd like to join up with, and I have about two months to get prepared for the easy ride they say everyone is invited to. I'm trying to get my children involved also. Does anyone here know just how safe (health wise) it is for children ages 6, 8, and 9 to be into biking? Any experiences?
