Road to the podium, Triathlon Training (GoPro)

Saw this at Youtube the other day and I can't resist but to share it.

After watching this video, it makes me want to get a GoPro camera myself and start documenting my own training! However, the title won't be Road to the podium, maybe something like "Road to cross the finish line" is more appropriate.

But oh man, they are not cheap at all, and again, it gets into the issue of stuffs that you need vs stuffs that you want. Just like everything else in life, there are tons of equpiments that you want for your Ironman training, but I probably have everything that I need.

Anyhow, has anyone used it? any comments? goods and bads? Anything will be helpful for me to make the decision on more toys.
