Course Details:

Start/Finish: 292 Concord Road, Weston, Massachusetts, 02493.

Race Day Schedule:

Pre Race Meeting: 7:45 AM

10K Start time: 8:00 AM

Half Marathon/Marathon/50K Start time: 8:15 AM

Course Description:

The Spring Classic course is relatively flat and smooth and is great for beginners, experts and speedsters alike. We carefully crafted a bespoke 10K loop out of an artisanal maze of twisting trails that runners will compete a number of times according to the distance chosen. For the half marathon and marathon distance we’ll add an extra little bit to get you to near your desired goal. We by no means guarantee you’ll get an exact distance but that’s half the fun!

The start/end of the loop hosts the course’s only aid station.

Strava Link

Course Markings: The course will be well marked with flagging all along the trails and with signs at any major intersections so that participants can easily stay on route (as long as they are paying attention!). Participants should be sure to review both the course maps and the course description beforehand to understand the general layout of the various distances. We recommend participants also download the GPX file and load it onto their GPS watches if they have one for additional reassurance. If you go off course on race day, you must backtrack, as opposed to making up your own version of the course. Review of GPS files will be done if it is believed the course was not followed by any given participant. Participants found to have not done the course as marked may be unable to get an official finish time. Please let the volunteers know at the aid stations if there are any navigation issues and we will work with you and others to sort them out.


Cut Off Times:

We love our volunteers and want to respect their time, as such we strictly enforce our cutoffs so that everyone can get home in a predictable time frame.  Over all the distances, Runners will have till 2:15 PM to start their last loop and must be finished by 4:00PM. Sweepers will be on the course removing markers at 2:30 PM and runners must stay ahead of them. If you anticipate needing more time to complete your race please contact us and we can potentially arrange for an earlier start.


If you are interested in volunteering we will need folks to help with the following:

  • Help set up/break down 

  • Check runners in 

  • Park cars 

  • Fill water bottles 

  • Stand in the woods shouting at people

  • Just generally have a good time outdoors

The volunteer signup sheet can be found here.

Trail Sisters Approved Event:


The TARC Spring Classic is proud to be Trail Sisters Approved! The commitment includes, when applicable, equal podium spots, equal prize money & awards, women’s specific swag & apparel, menstrual products at aid station parta potties (where applicable), and equal opportunity/space for women on the starting line. You can learn more about the standards and their awesome organization here.

Pride on Foot Partner:


Pride on Foot works with run groups, race directors, and fitness organizations who want to understand how to be more accepting and inclusive of Transgender, Genderqueer Intersex, Gender non conforming, and Non binary people. Through education and policy changes they create affirming, inviting, and safe spaces where everyone can be free to workout while living an authentic life.

Participant Camaraderie:

Whether you are competing for the win or bringing up the rear of the pack, we are all out on the trails to have fun and move our bodies in nature. All of our participants are incredible for just getting to the starting line, and you all have impressive journeys for getting there. On race day, we hope you will be everyone else's top cheerleader, cheering on and providing support for one another throughout the morning. Be sure to spread the love and joy with your fellow trail animals. We also welcome and encourage you to bring chairs and stick around after your own race to cheer on other participants as they come through the finish.

Running in the Woods & Weather:

Please prepare for all manner of weather, insects, critters, trail rash, etc! Historically, this race has fluctuated between nice and cool days and uber duber hot ones! In New England, we have to prepare for the worst and hope for the best!
