first - I am not an expert!
but it sounds like you need mental prep as much or more than leg prep. 7.1 is pretty good on a tough climb! I celebrate "not hitting 6!!" on many climbs.

So - you've done it. *Hooray!* You know you can get up Block House - and that you can maintain speed. Next time you approach this hill, take a look at it & tell it "HEY! I Beat you once, I'm gonna do it again!" As you ride out to this location, visualize the hill, and see yourself climbing smoothly over the top, and next time it probably won't seem so huge. New hills? you can compare them to things you've beat in the past, and suddenly it isnt' so hard. Or even the "just one minute more - I can do Anything for one minute" approach.

I've been there, and I KNOW that there have been rides that I let the hill beat me before I even started... even if I climbed one of those, it took a long time for me to mentally 'get over it' - far longer than it took to ride down the other side. I'm working very hard to Not Ride Grumpy too much wasted effort there!
