Day three had me completing the first crossing of the Sierra Nevadas, then looping back across the same mountain range for a second time through the Sonora Pass. Tioga was relatively consistent in how steep and windy it was (which was both), but Sonora was a much more gentle climb which finished off with a very steep and challenging ascent and descent. In retrospect, I probably should have found another way around rather than crossing these two high, challenging passes.
