Porcupine Mountains 100

Round 9

Ontonagon, MI

Porcupine Mountains 100

Presented by the Hamilton's North Coast Adventure

March 28, 2026


The Porcupine 100 is all new for the 2026 season, but the facility partners are no strangers to the Cor PowerSports Race Series. Steve Hamilton of Hamilton North Coast Adventures and Jay Mittlesteadt of Jay’s Power Center have been part of the series for almost a decade and will now host the series finale on the Hamilton North Coast Adventure property.

This past fall, Cor PowerSports staff, along with Zach Herfindahl, Steve Hamilton, and Jay Mittlestaedt, worked on a race route and trail clearing on the private property of the Hamilton North Coast Adventure facilities. Thanks to their hard work, local racers will now face a challenging 12-13-mile full-terrain course routed through UTV trails, fire roads, and fields.

North Central International has also offered a bonus payout for the Pro Factory class winner at this event!

Sunday morning after the race weekend, we will host our first-ever Year-End awards Brunch at the AmericInn in Silver City.
