Virtual training

So...we create a website of videos and blogs that house a library of
real actual videos of certain running/training clips. (i.e. the 12 mile
loop around the charles river, Acadia national park in Maine, Santa
Monica/Venie Beach boardwalk).

The videos would be shot from the first person perspective and could be
played at fullscreen and viewed while someone runs on a treadmill at
home or at a gym. Shooting from the first person would be a great way
to simulate the actual body movement while running/walking.

Additionally, we could set up a blog feature that allows usees to rate
or comment on the videos/training sessions and potentially upload their
own.
