After some thought about using the GoPro and my failed/planned video recording I decided to do a little ciphering At full HD on the GoPro which is 1920 x 1440 each image is about 7MB. Forty-eight (48) frames-per-second (fps) of video would create a file size of approximately 336MB per second. At that rate, one (1) 16GB memory card would fill up in about forty-seven (47) seconds. That can't be right, either way I think I'll choose a lesser image resolution and a slower fps rate for my next attempt. I was hoping to get about five (5) minutes of raw video to edit but it was not to be.
Update (1/13/13): My ciphering was wrong I shot four video segments the following weekend. With the camera settings still on the default 1920 x 1440 resolution. Segment #1 file size was 1.37GB for a 6:33 length video. Segment #2 was 3.66GB for 17:25 of video. That seems to equate to about 218MB per minute when converted to MP4 format. The same file is about 2.33GB per minute in the .avi file formate as recorded. I have no idea how that's possible. My computer says the 17:25 long .avi file is 47.5GB. I only had a 16GB microSD card. The GoPro learning curve must be steep and treacherous.

I have to say that my legs had not burned like they did on Sunday in quite a while. Therefore, I'm optimistic that this type of interval training will improve my power and speed on the road bike. I'm looking to improve my bike speed at Ironman Florida 2013 by around 20 minutes. Mountain biking should help.
One last thing. I have to ask myself, what was I thinking when I thought I'd be riding my MTB bike at night? It's hard enough staying on the trail in full daylight I don't know what I'd do in almost total darkness.
One more thing. My Bontrager RXL MTB shoes fix most excellently! I put them on, cinched'em up, and didn't even notice that they were there until I took them off two hours later.
Thanks for reading.
