The eight (ninth, technically) installment of my Running Azeroth series is up on YouTube. I've also gone through each episode and, in the video description, added the distance each video would be at each running speed. For example, Episode 8 at a walking speed of 3 mph is a 2.2 mile (3.5 km) walk. Running at 5 mph, this run is 3.67 miles (6 km); running at 9 mph, this run is 6.6 miles (10.6 km). I've also created a playlist of all of the Running Azeroth episodes, in order, for ease of use. I'll continue to add new episodes to that playlist.
The Kalimdor Marathon episode isn't quite as long as an actual marathon, though I'm working on a much (1.5 hour+) longer Eastern Kingdoms marathon for the next episode.
Put your phone, tablet, or laptop in the magazine rack of a treadmill/stationary bike/elliptical machine and enjoy these point-of-view running videos to explore Kalimdor in World of Warcraft. This run begins in northern Winterspring at Frostsaber Rock and winds south to the southernmost tip of Uldum at Schnott's Landing. The run goes through Winterspring, Felwood, Ashenvale, Stonetalon Mountains, Desolace, Feralas, Thousand Needles, Tanaris, and Uldum. Episode 8 is very fast (fast mount), and is particularly suited to stationary bikes and fast runners.
To use, just open your phone/tablet/laptop, stick it in the magazine rack of your favorite treadmill or stationary bike, set the video to full screen and run your way through Kalimdor. Location suggestions welcome; just ping me on Twitter or comment on YouTube.
