MK Marathon 2013 SuperHero

What a fantastic idea! http://www.mkmarathon.com/superhero/ Anyone including children can take part and complete a 1.6 mile course in a super hero costume. My little boy will be 6 1/2 next May and he has a Batman and a Superman costume. He needs an adult to run with him which is a pitty as I'll be too busy running the full 26.2 miles. Maybe I need to get a childrens team together and some kind parents to join in?
