The course is a 12.5 mile clockwise loop run entirely in Willowdale State Park in Ipswich,Ma. The marathon does 2 loops (plus a little extra at the start to spread runners out and get you to 26.2 miles), and the 50 milers do 4 loops. I emailed the RD to see if he had a course map (Mike Wade and I had planned to run the course on Thursday) and he offered to run with us instead. Even better!
I headed over after work and met up with several folks who were running the course. We would start at the south side of the forest (around the 4.5 mile mark). There were seven of us total, and I think 4 were G.A.C. members. Marty Sullivan (RD) was our guide and led us around the course, providing tons of detail about the course (aids stations, hills, wet sections, etc). The G.A.C. members were full of stories and kept us entertained for the 2 hr run.
We were joined by Chris, Al, Jim, Mae and Peter.
As trail races go, this course is pretty tame. It's a nice mix of single track and carriage roads, but I'd say a bit more single track. The trails weren't overly rocky or rooty (except a couple of short sections), and only 1-2 spots that were even remotely wet. One section you could run around the water/mud, the other section was a little tougher (about 3 miles in). Other than that, the trails were dry. This course is 100% runnable.
Typical single track
Afterwards Marty handed out a new course map along with wheel-measured turn by turn directions. I think he plans to post these on the G.A.C. website but I've included them below just in case. He also is planning a couple more training runs on the course over the next few weeks so if you're interested keep an eye on their website.
