No big ad campaigns, no corporate sponsors, no local or regional newspaper or TV promotions, not even the usual obligatory one-size-promotes-all beer banners with the name of the event emblazoned on a huge blank white spot.

Despite all the makings of what should be an unknown event, the Slimey Crud Café Racer Run in southern Wisconsin is attended twice each year, on the first Sunday in May and October, by riders from all over the country and routinely has participants from at least five states in the upper Midwest.

The Crud Run meanders across the scenic Wisconsin River valley from Pine Bluff in Dane county to Leland in Sauk County. The distance between the villages is less than 30 miles in a straight line, but the road mileage can vary from about 70 to, well, who knows? No specific route is prescribed, so the best way to go depends entirely on your imagination.
