Start from Fields Bridge Park in West Linn. The first 12.5 miles goes to Tualatin then Graham's Ferry Rd to Wilsonville Rd. The Graham's Ferry Rd paving project appears to be completed.

The second Ladd Hill climb gains 500 feet in 1.7 miles. Total climbing to the Bell Rd turn-off is 1800 ft. A nice, long downhill on Bell Rd, except for a couple short rollers, to Wilsonville Rd. Another short climb to Graham's Oak Nature Park then nice cruising into Wilsonville. There is a gradual climb on Wilsonville Loop Rd to Advance Rd. Afew long rollers on Advance Rd to SW Mountain Rd. Total climbing to this point is 2400 ft. Still more climbing on Mountain Rd to the fire station then a downhill to the Turner Rd turn-off. Finish downhill via Turner Rd and back on Borland Rd to the park.
