Anyone running this?  I'm registered and am hoping to stave off injury enough to make it to the start.  I'm 51 and have never run a marathon before.  I started running casually a year ago, with large breaks in training due to weather ( I live in a heavy snow zone), and two bouts of achilles tendonitis.  I've been running for 6 weeks now with pretty good results.  I am being cautious and never running more than 4 days a week.  I know BSIM is a tough run - with all the hills, so I'm just hoping to finish under 5 hours.  Anyone else?
