You can take the Interurban trail all the way down to Auburn - If you know about the Green River, the Interurban is in basically the same spot. You take the Green River trail down to the Starfire Sports Complex (the soccer fields). That's where the sandbags start on the GR, but the Interurban is clear of obstructions. Follow the GR through the soccer fields - where you'd normally go right to stay on the GR, go left/straight towards the Family Fun Center - then you are on the Interurban. It is straight and pretty much flat from there to Auburn.
If you don't mind driving a bit to ride, the Sammamish River and Burke Gilman trails are flat.
