Begin from Fields Bridge Park in West Linn. The first 17.5 miles covers the usual route through Wilsonville. Ride Borland Rd to 65th, then Sagert to 95th, Avery St then back to Boone's Ferry Rd. Veer right onto Ibach St then straight onto Graham's Ferry Rd. Continue to Wilsonville Rd. Turn left and ride through Wilsonville to the Advance Rd intersection. Instead of turning right onto Advance, stay straight onto Stafford Rd. Continue for about 2/3 mile to Homesteader Rd. Go right onto Homesteader. This is where the major climbing begins. There are 3 short climbs on Homesteader, all at 9% grade or greater. At SW Mountain Rd, go right and continue to Hoffman Rd. This road is brutal. The road becomes Pete's Mountain Rd at the bottom of a hill (Riverview Ct). In the 3 miles to Schaeffer Rd, there are several climbs, most over 10%, with one peaking at 16%. There is a little more climbing on Schaeffer Rd, but nothing like Pete's Mountain. The final 3 miles are nearly all downhill.
