This is a great thread - my lungs give up before my legs do, too - sometimes I just need a few deep breaths - after I get enough air, my legs are willing to keep going. Everything is stronger, but I'm still moving a 200+ lb body up a hill! If I look to the top of the hill, I never make it - I focus about 10 feet ahead and mentally chant - my/legs/are/strong, my/legs/are/strong to my pedal strokes. Usually at the end of my ride, I do a standing climb on the last hill - got nothing else to work with but gravity at that point. Right now, needing to just ride and ride and melt some poundage, I give myself permission to do whatever it takes, figuring finesse will come...eventually.
