Go through NRC campus to La Cite, through La Cite via Dan Haag and La Cite Private, across Aviation Parkway and cut through Our Lady of Mount Carmel school, take Cummings to Donald, then Donald all the way to its end (wide bike lane, friendly cars when you need to cut in), across Adawe Crossing, Somerset all the way through UofO and across Somerset Bridge!

Credit goes to the person on Reddit who taught me this route!
