I ran with a phone tracking me on mapmyrun.com (track here: http://www.mapmyrun.com/
I had Phoebe Seltzer run mile 33-62 on the route with me (so this partially overlaps with the mapmyrun.com track above), and here's her track of those middle miles: http://www.movescount.com/
Lastly, I had Matt Howard join me from mile 62-finish and capture it on his GPS watch: http://www.mapmyrun.
I don't know how to extract metadata from photos (along the way), but I've attached a few from the start (me in pink shirt/backwards hat), Graffiti bridge, Mt. Wachusett summit, a random (but beautiful) field along the way, and the finish.
