Got up early for this ride to beat the afternoon heat. Warm and humid morning. Started from Lewis and Clark Park in Troutdale. The first few miles covers the historic highway to Stark St. bridge. Cross the bridge and after a short climb turn left onto Kerslake Rd. Then the route goes left on Division and up Oxbow Drive. Could not make the usual turn onto Altman (road closed) so had to continue the gradual climb to Hosmer Rd. Left at Lusted Rd to get back on the original course. First quick stop was at Dodge Park (mile 13.5), followed by another climb to Thomas Rd. Continue on Thomas Rd to Ten Eyck, then it's the Shipley Rd climb. Steady 5-7% for 1.7 miles to the Marmot Rd junction (mile 18). Nice downhill on Marmot Rd to Ten Eyck, followed by another steep climb (8-10%). Decided to ride Coalman Rd, which is a left-hand turn on an uphill hairpin on Ten Eyck. Rode nearly 3 miles on Coalman Rd, with another long climb. Returned to Ten Eyck and finished the last long climb into Sandy. Continued through Sandy to Bluff Rd and took Bluff Rd to 342nd Ave, which eventually becomes Cottrell Rd. Finished via Hosner Rd, Oxbow Dr, Stark St. bridge and the historic highway back to the park.
