Mass Start events are about community and doing hard things together. The Crusher MS format is harder than your average gravel event. The experience will test you. You will learn about “Yooper Math” and “Checkpoints.” You’re not gonna find a better place on Earth to spend a weekend or a better group of people to spend it with. All MS events begin and end in Copper Harbor (loops), except for the P2P, which is a point-to-point.
