My son (8) and I rode the C&O and Great Allegheny Passage trails from DC to Pittsburgh last summer on our tandem. Had a great time and am considering riding the Erie Canal from Albany to Niagra Falls this summer. Has anyone ridden both trails? I'd like to get a good comparison of the trail conditions to know what to prepare for. We thankfully put 700x32s on for the C&O ride and probably would not have made it in the 28s we usually ride. Can we do well with 28s on the Erie canal or shold I up the tires to 32s again?
