so I've really been suffering when climbing (San Jose area) for the past month. Rides that I normally can have a go at, I've just been suffering thru or haveng to just put it in the lowest gear and spin up...was it the holiday weight gain? the cooler weather? the week I took off to go back east? This past week, more of the same, two normal rides for me = suffer fest, nothing in the legs or lungs and really getting discouraged to the point that maybe I just need to take some time off? And then on Sunday I did one of my usual rides and presto, I fly to the top (for me) with my 3rd best time ever and had PLENTY in the tank afterwards, I could have beaten my best time np. How did I suddenly go from a month of suffering to a day of glory?!?! ;-)

In all seriousness, any explanations or one of the mysteries of cycling? I'm betting when I go out tomorrow or Wed, back to the suffering...very positive of me.
