Climb to Kaiser is a great ride. Sadly, I missed it this year due to the flu.

Kaiser climbs, and climbs, and climbs again. Tollhouse is a nice, consistent climb that finishes off with a 17% grade. It's not terribly long. Big Creek is a beast. Very steep, very exposed. Bring your lowest gears for this one. Kaiser Pass is another great climb. It starts out pretty easy, but then it kicks up towards the end. After climbing most of the morning, the final push up to Kaiser Pass can be tough.

Each of the climbs are decent by themselves, but they're quite the challenge when you put them together.
