Norse, this is a little longer than the way suggested by Greg, but it offers somewhat less of a climb over Mt. Tabor. Also, it may be a little easier to follow, as most of it is just running straight out Se Harrison/Lincoln. Plus, the circle at Ladd & the rose garden are a cyclist's delight.

Greg, if you haven't tried this bikely.com mapper, give it a whirl. Far superior to the gm-ped, what with the ability to add cues & comments.
