SethBling made a map using a MCEdit filter. It is a parkour course with 1000 jumps and keeps track of your best, number of attempts, and current block. It is also multiplayer friendly.
I figured some of you would like to give it a try. I know I don't though ;o

But at least I have gotten some of the harder jumps down.
