Rode part of the Interurban along with the Green River Trail at the end of Sept 2009 with a dozen 3 wheel recumbent riders. The two trails have very little elevation change even if the above elevation graph looks like a mountain climb. Trail was in great shape, very clean (no flat tires) and was not heavily traveled on a gorgeous sunny autumn Saturday.

You have to look at the scale on the left of the graph — the elevation varies from 28 to 88 feet of elevation, so there is a total of one 60 foot climb over the course of 10 miles. In other words: nearly completely flat!
Which is why I marked the trail as “flat” in the category section as well. :)
