Nipmuck Trail Marathon -

Trail markings were very obvious. The trail is marked with blue "blazes" (more later), and most of the turns where an inattentive runner could get lost are marked like this - very obvious. A runner would really have to be oblivious to miss them.

There is one section in the second half where the main road goes straight and the trail goes left, which made me stop and look around. Following the blazes kept me on-course. That was the only one which caused me any confusion.
