Trail running videos for your treadmill workout

Running on a treadmill can be a tedious affair.  The tedium can be even more acute for trail runners who are accustomed to enjoying the sensory stimulation of running in nature.  I usually listen to audiobooks if I have to do any treadmill running, but I recently found another alternative.

There are a number of channels on YouTube with videos of people running trails, so you can do your run on a treadmill and watch a first-person view of a beautiful trail run.

I've included a few below, but just search for "virtual trail run" and you'll find plenty more.
