I love long climbs! GMR/GRR that starts with a 7.6 mile climb, Angeles Crest, Hwy 39, all the Long Climbs on the Knoxville Double . . . all very good and great fun.
My friend Laura calls it "the Zen of climbing." I don't know anything about Zen, but it does seem like a semi-meditative state when I'm climbing for hours on end. Sure, I love descents too, esp. the winding type with switchbacks; all good!
