A lot of hill climbing

Last night I went hill climbing at Cloverdale road.  There was 6 of us from the team, going up and down, back and forth for over an hour. I felt a lot better than when I did this last year. I was able to stay seated and grind it up all the way. The IM Canada race is going to require a lot of hill climbing so I need to do this exercise as much as possible. I am also considering a new rear cassette that will give me a bit of better chance on the hills I currently have a 11-27 cassette and I can get a 12 - 28. Which means I will not be able to go as fast on the down hill, but it will be slightly easier to keep my rpms up on the climbs.

Ideally I would be spinning at 90 rpms. When the hills get too steep the rpms slow to 70 and that will burn out your legs.
