We really like the letters on this logo, symbolizing a trail itself, but the C and G should not be connected.
Also, we hope the trail network will be known as just the "Green Way" without the Camden, when it leaves Camden City and Camden County, so Camden should be secondary to the "Greenway".
The triangle is the favorite, because its symmetry appeals to us. The trail inside should be more symmetrical itself. Now it appears also a meandering river instead of a standard style trail all the way through. Perhaps it's the perspective you're trying to achieve. I think it could be tweaked.
A bicyclist is a good idea, but the graphic you chose makes him look confused.
