Mountain biking is hard...

but also lots of fun!
Christmas Day ride - 12 miles, 2100 feet of climbing (and descending! :D). Most of the climbs are a 12 percent average grade, but there is one half mile section we did yesterday that is an average 16 percent. Of course just at the top of the steepest section, there is a cattle gate. I got to it first yesterday and couldn't open it. I thought it was because I was so oxygen deprived that I couldn't figure it out. Actually, it was jammed. :p
