Equestria Games: Think out a pony sport!

[Declen 118]

Can you invent a pony-specified sport for Equestria Games?
Not just like ponies playing something we do. Using racial traits and having race-mixed teams would be a nice start.

My suggestion would be a sky-biathlon.
A pair of pegasi pulls a  sky-chariot with a unicorn onboard. Competition consists of:
- A race through a pretty long distance (20-30 km);
- passing an obstacle course (pegasi must be careful so unicorn doesn't fall out);
- stopping at several shooting positions placed en route, each time unicorn must hit a distant target with his magic.

What are your suggestions?
