I will admit their is a method to climbing. Knowing when to get off the saddle and when to stay on the saddle. You learn it through trial and error. And what works for you on climbs may not for me. I have stayed off the saddle for about a mile on a climb which sounds crazy but I was in a groove and it felt good and worked. Could do it again on same exact portion of that climb and may kick my arse.
Thing is do not get too caught up in this and push it each time on the climbs until you feel like you have no more left and I am sure your going to get better.
Reminds me of a story I heard many many years ago........not sure it is true but it was told to be true. A guy was told he was dying so he began running to hopefully have a heart attack and die. He would run until he collapsed but not die. Each time he went out he got better and ran further until he was in phenomenal shape and no longer dying. Like I said, not sure this was true but it was portrayed to be a true account! If it was true what a story for sure!
