Great job, I have seen quite a few of these vids and your's may be one of the more polished. I liked the occasional 3rd person inserts from the roadside which did a nice job of breaking it up, the mix of commentary and music, the dynamic course map. Sadly, the downhill bit starting at 4:30 has me itching to leave work to get on the bike early and I've still got 3+ hours to go.
The only other helmet cam movies I occasionally watch are the chavezcycling fliks - mainly because I like the same catchy tune he plays on most of the vids. Ironically the majority of comments seem to be asking he remove the annoying music /img/vbsmilies/smilies/wink.gif
