The road is. in a word, grainy! Seems like the first portion once you leave Woodland park is regular cracked concrete then it turns to what looks like packed sand and glass. There was pebbles everywhere and if you are behind a car they will peg you in the face for quit awhile. Turns back into the regular concrete right before the end. The crappy thing about it is the road is the same color as loose sand/gravel, be careful.
Here is my vid of it today...Just got a GoPro960 Monday (B-day present from wifey) shooting it in standard def just to see the difference between it and HD (Huge, stand def very grainy) and attached to the bike compared to the helmet (Extremely shaky on bike)
