There are many fenders this long, like PB Cascadias and SKS Longboards.

Finding a fender with enough "front extension" is the hard part. I like a fender that extends past the highest vertical peak of the front wheel and starts to curve downward. This assures that the spray is directed downward and not up where I just ride into it.

The other nice thing about aluminum fenders is the rolled edge. Instead of dripping off the sides and onto my feet or rear mech, the runoff generally drips off the front or rear of the fenders. This keeps things much cleaner.
