I saw this a couple weeks ago. After about six minutes of thinking I registered for it. It's a race from the southern Wisconsin border to the shores of lake Superior.
Currently the race is set to follow the Trans Wisconsin Adventure Trail. As far as I can tell the route was laid out by adventure motorcyclists. It's a mixture of singletrack, doubletrack, gravel and logging roads. There appears to be a bit of pavement in there as well. I guess I know when I get there. More to follow on this.
