Saturday morning I ran up and down the entire length of Leif Erikson drive for the first time. Leif Erikson (sometimes spelled Leif Erickson instead) is an 11 mile dirt and gravel road, closed to cars but open to bicycles, that winds through the lower slopes of Forest Park.

Leif Erikson Drive, Portland. Click for larger. Map data from Google, the blue line showing the path is from my GPS.
Here’s an approximate elevation profile; mile 0 is the Thurman Street trailhead and mile 11 is Germantown road.
The run took me about three hours and fifty minutes, which means I averaged around a ten minute per mile pace. My left calf was cramping a bit by the end, and the tendon in the back of my left knee (in the poplitea fossa: the “kneepit”) is still a bit sore today.
Thanks! I was searching online for a good running route around beaverton – this was all the info I needed! :)
Thanks friend. Now I know which end to enter for a downhill ride. Happy running!
