If you want to start with the best part, the last 40 minutes of the race:
Or, here is the full 1:28:
Last year [in 2010] I brought my little Panasonic Lumix ZS3 along with me running the escarpment trail. I sawed off the top of a hiking pole with a camera mount on it and added weights to the bottom, creating a kind of cheap steadycam (see image at bottom). The Lumix, like many newer small point-and-shoot cameras, captures HD video that isn't bad. I tried to process that video last year but it was in a difficult format, my computer at the time was too slow, and I soon got very busy, so it had to wait until a somewhat more inspired run for me this year to finally post some of it.
I started shooting video when nearing the top of Blackhead Mountain, about halfway into the course, and continued filming all the way down to Dutcher Notch several miles later. That video is about 48 minutes total. Then, after changing to a new memory card and battery at the aid station on Stoppell Mountain, I began filming again just before North Point, and continued all the way to the finish.
The year before I had worn a GoHero headband cam to capture video and photos, but somehow the seal didn't work and it got soaked and only a certain amount of still photos survived. I realized though that the helmet/headband cam was quite jerky, and of course only looked where I looked or in a fixed relation to where I looked. More often than not that meant the camera only captured what was right in front of me -- the trail, and when I was following others, their backside and butt. It was very uninteresting, and I thought not fair to the runner in front of me: very few would want images of their butt show as part of a photo gallery of a race or in videos.
The above is what led me to try using a handheld camera mount, so I could direct where the camera was pointing easily, avoid filming people for the most part, and try to steady the image somewhat by adding weights on the bottom of the mount. I think it worked pretty well, considering that I was mostly running on a pretty nasty trail most of the time. But the footage can still make you ill when watching on an HDTV. [Now it's much more watchable having run it through the YouTube stabilizer].
This is the makeshift steadycam. The camera and mount were about 3 pounds, which I had in my pack for the first half of the race, then carried in my hand(s) for the last 2.5 hours, filming about 1.5 hours:
