I ran a 5k yesterday with my 11 year old son. This is an experience no parent should miss. We've been doing some easy training now for about 3 months. He's actually run 3 5k's and on Saturday he pr'd by about 2 minutes. There is nothing like seeing that smile on his face after finishing. If you have kids old enough to run with you do whatever it takes to get them run with you. you will find its much easier to talk about anything while out on a nice easy run and you will build memories that you and your child will never forget.
