Just got back from the ride. We started in Stuart and rode to Valentine. 85 miles each way. The limestone is a little thick due to minimal traffic but not unrideable by any means, however, there has been some cattle and horse traffic so some of the stretches were bumpy for around 100 yards in a few spots. One stretch just north of Johnstown was so bad I had to walk my bike for about a 1/4 of a mile because the trail was so rough. I jumped on highway 20 after that all the way to Valentine. A friend continued on the trail and said he came across a lot of washboards up to around 6 miles south of Valentine.
On the way back I took highway 20 until Basset and was much better. Minimal hills for a few miles but flat the rest with good shoulders. You could take highway 20 all the way to O'Neill with minimal hills and still have a good ride, or hop on the trail for a change of pace, but highway seemed faster and more comfortable in the long run. We had several flats primarily south and north of Ainsworth with thorns and one or two on the rest of the trail also, but highway we had no flats.
Regardless, the scenery was great and we'll definitely be doing it again next year. Hope this helps. Let me know if you have any other questions.
