These are things I've seen recently that I thought were interesting
On Board Cam with Emma Moffatt - 2012 Mooloolaba World Cup - this is the first type of video like this I've seen.
This is an ITU race which means that it's draft legal which is why you see bikes around her all the time.
This is a running track that has a built in hill. That's a pretty neat idea. It came from this website (http://www.toxel.com/inspiration/2012/03/26/3d-athletics-track/)
The next two are a guy doing sort of funny Skittles ads.
A month or so ago there were videos going around about what people say - here's a video about what triathletes don't say. Personal favorite line "I've got so much time, I don't know what to do with it"
