Sorry I missed the "AND BIKE" part of the sentence.

However I have portaged my bike with the top tube lodged between my Gregory Day and one half pack and my shoulders. My panniers were clipped to the pack's side compression straps. The distances used were relatively short such as climbing from one drainage to another in the Andes in Ecuador or to reach a refugio on a volcano in the snow. Just how far do you need to carry both panniers and bike?
