The O2S is a point-to-point race, with riders gearing up at the start line in Negaunee, where in 1844 iron ore was first discovered in the Superior region. The long distance course travels through Ishpeming, past towering head frames from the heyday of underground mining, and then heads north into the beautiful wooded wilderness, crossing or running along side of the Dead River all the way into Marquette to the Lake Superior shoreline. The shorter race also starts in Negaunee, but immediately turns north and then east towards Marquette. The two courses merge six miles north of Negaunee and the soft rock riders get to experience the same Dead River and Superior overlooks as well as the same finish line. The 28-mile Soft Rock and 48-mile Hard Rock races offer a challenge for every level of rider. The outstanding support by hundreds of volunteers makes racing and riding the course an outstanding experience.
