Here is a little parkour mod that i have created, i have tried to create some unique obstacles.

You start with a little jump, then you climb across a wall, go up a pole, go down, go through a path of balls, go up a slope then finish.

UPDATE:
Anothe parkour mod, quite a bit of climbing in this one.

Go up the slope, climb a wall, run, jump through the window, go down (try something creative), run, jump and finish.
