This is an interesting, and quite long (about 1hr), video where Red Bull sports photographer Chris Garrison explain how he did some of his shots using the PocketWizard HyperSync technology in the PocketWizard FlexTT5 and MiniTT1, which enables you to shoot with studio strobes at very fast sync speed, up to 1/8000th of second. Pretty cool stuff.

If you want to know more about this technology, you can find a brief explaination on this page.
