There are 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.

Its origins are nearly as murky as Stonehenge, dating back to the early Seventies, according to one of its co-founders, former Triumph/Bultaco/Matchless racer and former Triumph dealer Lyall Sharer. From humble beginnings, the event has become an organic thing that thrives on its own energy. At each gathering, it isn’t uncommon for anywhere from 1,000 to 3,000 machines to show up.

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.

Despite the name, the event is not limited to the sheathed-in-plastic sportbike set. In fact, while there’s something for everybody in every class of bike, the event seems much more like a rolling vintage and classic bike show.

It’s a scene you really need to see to believe, and you can get some of the flavor by taking a quick tour of our photo gallery on our facebook page for pics of some of the unusual and great vintage machines that have turned out for recent Slimey Crud Runs.

Of course, there’s no substitute for being a part of the real thing, and fortunately, you’ve got two shots at it every year.

The Fall date for 2020 is Sunday, October 4th.
