I ran the Highlands trail yesterday in a time of 3hrs 29min 25sec. It measured 34.97km on my gps. I ran it counterclockwise in the "recommended" direction. It was a super fun trail and the last 15km were fairly technical and hilly! I will post a link to the gps file once I get home after the weekend.
