LOGO 2 & 3, I like the little runner. See how it looks with all the legs and arms coming out of the red circle like the right side. I don't care for the black lines on the left. The font needs to change. Think sporty or fast. RUNNER needs to stand out more than ZONE.
Entry #7. I like this one. Enlarge the whole RUNNER ZONE so that it's the same height of the circle. Enlarge or stretch the word ZONE. I liked the runner better when the arms and legs ended right when it came out of the circle (#2). Try to make all the legs and arms end at this point.
