hi, I made some changes on and color modifications too.
I think that your original colors (deep blue, green, black) is good because each one can represents one discipline in triathlon, (blue - swimming, black - cycling, green running). that was first idea in #2 logo which each stripe represents one discipline.
#7 have bolder and better font and #8 have 3D effect applied
#14, good color change however the title seems to get lost, harder to read also it would be good if the icons could be created to move so it looked like they were doing each sport, good for websites, any chance of doing flash or is that out of the parameters?
