I guess I am just a Photo Realist..... but the wires are there!! That is what was THERE!!!! You are doing Sports Photography, not Fine Art Photography. I wouldn't worry about it.
Sure, you could spend a week cloning out the wires in PS but why? Maybe I would do it to my favorite of the images to put in a portfolio, maybe not.
Just curious, what did the other people shooting that race do with the wires, if anything?
Its kind of like when I gave my Mom a photo of my niece in the swimming pool; my Mom said, "But her hair is all messed up!" It's like yeah, she is 10 and she was SWIMMING!!!! It is part of the picture!!!
When you bike race or anything else on a city street, there are telephone poles and wires.......they have been there for a hundred years now in most cities.
