NEW!!! Tag Team the TARC100 NEW!!!

As Trail Animals we believe that no animal should be left behind. While many of us think nothing of running a 100K or 100 miler, there are many more who are “new to the game” or just coming back from an injury or a long winter of hibernation. The TARC Trail Series now culminates in October with the TARC 100, and we want to make sure the every Animal has a chance to push themselves, enjoy this gem of a course, and have a reason for the whole pack to come out and celebrate a tough year of training and racing. So . . .
We are introducing the TARC 100 RELAY! What better way to celebrate the New England autumn than by getting a bunch of your furry friends to tackle the TARC 100 together? Your team can now tackle 100 miler together. The basics are simple:
- Teams of 2 - 4
- One person per loop (25 miles)
- Team members can run more than one loop (with a team of 2 in the 100 mile relay, both would run 50 miles – can decide if you go all at once, or alternate)
- You can travel as “crew” to cheer on your team’s runner during their loop
- Your team can camp out at the start/finish
- TARC 100 t-Shirts for everyone on the team
- Finisher’s prizes for everyone on teams that finish their chosen distance (so make sure everyone is ready!)

This is still a mighty challenge – even a single 25-mile loop on this course can take up to eight hours! But we wanted to make sure that all animals had a chance to come out and experience and share the end of the season, and see for themselves what, exactly, is behind the challenge of the TARC 100.


Welcome to Massachusetts’ first 100 miler!  Hosted by the Trail Animals Running Club in beautiful Westwood, MA on the Hale Reservation. About 20 minutes from downtown Boston, the race will be run on a 25 mile loop course: 99.9% trail, 2,500 acres of private reserve land, a cumulative vertical gain of 8,000 feet of climb and 8,000 feet of descent for a total elevation change of 16,000 feet, with aid every 5 – 6 miles.  For 2015 we have changed the 50M to 100K. Start time is 5:00 am Saturday for the 100 miler with a 32 hour limit to complete the course. The 100K mile run will start at 7:00 am Saturday with a 16 hour limit.

What to Expect

You can be guaranteed of TARC's great volunteers, aid, course markings, and trail 'tude - we support everyone in the pack.  In a first for TARC, there will be custom embroidered TARC jackets for all 100 mile finishers and exclusive TARC technical t-shirts for all 100K and 100 mile participants. Additionally, every 100 miler finisher will also have the opportunity to purchase a commemorative shiny brass and silver belt buckle.

We'll see you in October!

Unaccompanied Minors and Animals

Due to Town of Westwood and our insurance policy for the event, no pets are allowed on the course at any time.  You can bring your dog to the start/finish area but it must be on leash the entire time (there is a strict leash law in Westwood). 

Minors under the age of 18 must be accompanied by an adult guardian at the event at all times. This is an explicit requirement of our insurance policy and of course a common sense precaution given the nature and length and timing of the event (i.e. at night, up to 30 hours, in the woods in a strange place).  If they would like to help out at aid stations and such that's great and will be welcome, as long as there is an adult guardian with them.

Camping Available!

We'll have Friday and Saturday night camping available right on the premises!  There will be NO sign up for camping spots but instead taken on a first-come, first-serve basis until they are gone.  More info to follow.  We are not allowed to have open fires so plan accordingly. This provides runners and crew an opportunity to choose to spend Friday and/or Saturday night on the course, under the stars.

Buckles Are In!

The custom designed nickle and bronze 10" belt buckles for all 100 finishers who cross the finish line in under 30 hours are now available to view as the first one has just come hot off the forge over at Colorado Silver Star, who also are the makers of the Hardrock Hundred Endurance Run buckles.  Check it out by clicking on the links below to pictures of this beauty and if you haven't already expressed an interest when you registered in buying one of these when you finish (~$50-55), send us an email and we'll reserve one for you (  It'll be waiting for you at the finish! There's a picture of the buckle at the top of this page. Schweet!!
