Biking to Petoskey

A friend and I are biking to Petoskey to rendevous with teammates and then watch the triathlon on Aug 21st.

Does anyone know of a good way to piece together a non-highway route to the tip of MI from Lansing? My only idea thus far is using Google Maps to piece together a route, but if someone already has a route, I’d appreciate being able to see it.

Thanks.
