I did it!
Richmond was a fantastic race. The weather was nearly perfect. And I finished in 3:22:56, beating the Boston-qualifying mark for my age group by 2:04.
I've written a full recap over at the DART blog, so if you want the narrative, head over there.
Here, for your perusal, is the hard data of the event.
Note that I did manual lap times for each mile when I passed the official marker, so you'll see that many miles are "off" by .01 or .02. All in all, I think this is a much better way to do this than using the auto-lap. Much easier to keep track of where you are relative to your goal.
