The logo really needs to highlight the fact that this is a running event. Not necessarily showing a runner, but something with a running theme. Also, we've been asking designers to incorporate the idea of 'choose-your-own-adventure' somehow in the logo. We're looking for creative ways to express this and not simply with text.
I prefer a non-circular design like #30, and using the word 'for' instead of the number 4. Thanks!
