This is my favorite race of the Xterra So Cal series. What a fun and challenging course. You start off with a blazing downhill, followed by about three miles of gradual climb to around 900ft. then back dwon into the valley until Mile 6. You do a gradual climb until mile 7 then you hit “The Wall”. This is 3 miles STRAIGHT UP until mile 10. You climb to around 2000ft. THE VIEW IS WORTH IT!!!! The last three miles is a super fast downhill fury.
