Just a game of SKATE.
Cepeda is an 'amateur' and Trent McClung is the pro. I have read that since this video dropped Cepeda has some sponsors now.
Note that McClung describes Cepeda as "consistent". That's not the best of compliments in skating; it's what you say about a guy who's style is boring but drops tricks like a metronome. On the other hand: consistency is itself a style. And it works for a competition like this. Watch some of the other videos to see what it looks like when the tricks aren't performed by flatland savants. McClung is really good at this, but Cepeda is a specialist.
