Our big event on my local trails, Hartman Rocks is the Original Growler which is put on by my friend and mountain bike OG Dave Wiens. It's offered as a 32 Mile Half Growler which is one lap of the technical singletrack course. Full Growler riders do two for 64 Miles. I have done the full a couple of times myself and can verify it's pretty hard!
I spent both Saturday and Sunday out on the trails shooting photos, averaging 1000 per day. I primarily used my Tamron 28-75 with a flash on one camera and my new (to me) Pentax DA* 60-250 f/4 on another camera with a monopod for stability. I really like that new DA* lens!

Every finisher of two laps gets a Growler (64 Oz beer jar). Looks like this guy sure earned his!
