i'm liking what you are offering. i'm now quite set on using blue black white in the logo. the shirts that are available for printing are white or blue, maybe black which could now be my preference
perhaps changing the font of #47/
#48. playing with that space between the letters.
#69 is also very dynamic. no gradients possible for the logo on the shirt. i see the R and the T.
try playing with the shapes more to represent landscape or roadway or water which is already starting to happen. i do like the placement of the text below. too thin a font may not print so well (for running tours)
maybe taking some form from the runner on my home page.
