Join the Trail Animals Running Club for the 2024 Don't Run Boston at Blue Hills Reservation, with 50K and 50 mile distance options! One of the region's true classics! It's twisty, turny, rocky and unmarked. It's cheap and fun. DCR Blue Hills Reservation is located about 10 miles south of Boston, covering an area of about 11 square miles. The TARC Don't Run Boston course starts and finishes at Houghton's Pond. The course has many turns and navigation is as big an obstacle as the rocky hills for new runners. If you can't train on the course your best bet is to follow someone on race day that has run before. The "Trail Animals Running Club Don't Run Boston", or "DRB" as it is now referred to, grew out of the desire to add more trail ultras to the New England schedule in the 1990's. At that time Howie Breinan was a graduate student at MIT and one of the early members of the Trail Animal Running Club started by Chris Haley. There were just a handful of true ultras in the area... primarily the Vermont 50 miler in the Fall and the Vermont 100 miler in July. The Nipmuck Trail Marathon was well established, but only 26.4 miles. The Pisgah Mountain Marathon in New Hampshire also claimed baby ultra status at 27.7 miles before stepping up to the 50K distance in later years. DRB may have beat out Don Allison's Bay Circuit Trail 50 by two months as perhaps the first true Massachusetts trail ultra.
