About this event

The Bike Jam has scenic routes through eastern South Dakota with course distances of 25ish, 60ish, and 100ish miles. The event is for all levels of gravel bike enthusiasts with the 100 mile course having a $10,000 prize purse attached to it. A couple signature items of our race is an aid station at a German Hutterite Colony and a finish line that has a raised stage with live music playing as riders finish under the stage.
