The original Mileage Club® Challenge Series includes nine runs and awards, as well as tons of helpful information on how to conduct fun runs at schools, clubs, youth agencies and in communities. Challenge Series 2 has 13 supplemental fun runs. These fun runs are as creative and clever as the original Challenge Series. The main difference between the two, Challenge Series 1 and Challenge Series 2, is that with Challenge Series 2 you have the option of purchasing each run separately. The Challenge Series 2 CD allows you to personalize and print the flyers and certificates in color or black and white.
