The cue sheet and GPS links for the 2013 running (riding?) of the MA 600k have been posted on the event page. Ride safe and try to stay cool out there!
If you can’t make the MA 600k this weekend, be sure to check out the VT 600k in a few weeks. The hard working volunteers in Vermont have made the route even more scenic and enjoyable so some sections will be new this year. More info on the VT 600k event page.
