When people look at the logo they immediately need to "see" that it's a run.
They need to think- fitness, fun. A HUGE component to our Fun Run is that we build leaders in the process. Character, Leadership, and Fun is a big part of it...not just the run itself.
The check marks look cool but to me but don't communicate the above. Keep trying. You can even put the motto "Building Leaders" somewhere.
I think sticking to 2, 3 colors max, is important. I liked the star with a shoe inside of it on the other logo. Change color scheme and make the symbol more central. Simple is key for kids, and futuristic symbols. Like pixar, toy story, jimmy newtron type cartoon feel. thanks.
