I wanted to do this long climb up to Waterville to tag onto a ride I did last year that went up through Plymouth to Campton. Started with the Center Harbor Neck wall, but the view from the top over Squam is spectacular. Had a flat by Lake Waukewan but had the company of the former Fire Chief of Burlington, MA (Callahan).  Nice day, though humid, was no wind and fairly cool in the 60-70's up to Waterville. The long 13 mile climb up was steady and felt pretty good. The last mile up to the ski area were 6-8+%, but made it up. Went into Waterville Village for a refueling.  My legs were tired after the Waterville climb. The 9 mile descent was nice, but it was noticeably hotter at that point, into the low 80's. The hills were harder, especially the slog from Holderness School to Holderness and the Rockwald/Deephaven wall up to the Rattlesnake parking lot. Legs were completely shot at the end, but great to have done it.
