For that kind of distance in 24 hours, I would definitely try and ride the road bike. But, the biggest tire you can get on that thing is probably a 700x28, maybe even only a 700x25. If you can get the 700x28, you will be fine. You will just have to be very careful, especially at night, because there are a number of loose sections and quite a bit of debris on the trail that make it easy to go down. If you can only fit a 700x25, I would not recommend it...that's just too small of a tire for the the conditions of the trail. Whatever bike/tire combo you go with, make sure to get a tire that has a Kevlar (or equivalent) liner in it so that you won't get flats. I also recommend a heavier duty tube, sometimes called a thorn resistant tube. This combination will pretty much assure you that you won't get any flats unless you hit something major. I used this combination in October and over 293 miles did not get any flats. Again, good luck!
