MTB - Sam Merrill Trail, Echo Mountain. Altadena, CA 

Nice video. I was hike there today in the morning. Whole route was up hills from start to end. Walking hills 1 hour and 40 minitus. 2.6 miles. I bet bike is even harder and harder then walking. nice job

lol i like the metal core when you're going like 5 mph. planning on checking out this trail, will have to play this on the headphones on the ride down
