I am seriously considering riding the GAP this October with Kmehrzad, and perhaps someone else from TE. I do understand that it is crushed limestone, and I need to find some limestone to ride on to see what I think of it. I've heard of an appropriate trail in Ohio that is 20 miles or so in length that would likely give me an idea.

I do have arthritic hands - have other ridden this trail with the same problem? Of course I would have a steel bike - probably my LHT, but am wondering what it might do to my hands to ride so far on limestone - so it would be quite interesting to read experiences of those who have gone before me
