Please note: This race sells out, and there are no refunds, no transfers, and no deferrals (except for emergencies)!

Saturday, June 29, in Milton, Massachusetts

Race Start Location: 1904 Canton Avenue, Milton, Massachusetts (Blue Hills Ski Area Parking Lot)


The TARC Blue Hills Skyline Trail Run is a gnarly, old school 12K race with approximately 2,300 feet of climbing. The course is on the Blue Hills Reservation North & South Skyline Trail. The terrain is rocky and steep and will demand your attention, balance, and agility. In addition to epic staircase climbs and tumbling rock downhills, runners can expect a classic New England path through the woods with East Coast technicality and scenic views of the Boston skyline (if you dare to look up from the rocks under your feet)!

GPX File

Course Description: The course starts at the Blue Hills Ski Area, runs along the Accord Path until you hit the Skyline Trail.  Follow the Skyline Trail and blue blazes up to the top of Great Blue Hill, and take your first right to follow the southern Skyline Trail. Follow this to the first road that crosses near the Blue Hill Reservation Headquarters. Cross the road and see the aid station.  From here to the next road is an out and back. Follow Skyline until you hit the road past Buck Hill, then turn around and go back to the aid station, and cross the road and follow the northern Skyline Trail back to Great Blue. Take a left and follow Skyline to Accord Path and back to the finish in the parking lot. 

Course markings: This race is not for the directionally challenged or faint of heart! Course markings entail only the Skyline blazes. It is the participant's responsibility to be aware of the course beforehand. Everyone is encouraged to study the online map beforehand and download the GPX file to their watch if necessary. Participants can also print out the map ahead of time and bring it with them on the day of the event. At the request of the DCR, please stay on the race course and be aware that cutting around people on the trail causes trail erosion.

Aid Stations: The course has one aid station at the road crossing that you will pass twice (once on the way out and once on the way back). Aid will also be at the start/finish. Participants are required to have hydration packs or handheld bottles with them due to the minimal aid available.

Leave No Trace: The TARC Blue Hills Skyline Trail Run has a Leave No Trace policy. Please adhere to the Leave No Trace principles during the duration of the event (and we hope whenever you are out in nature).

Land Acknowledgement:

The TARC Blue Hills Skyline Trail Run is held on land that is home to the Pokanoket Nation, descendants of the Wompanoag people, the original stewards of this territory. We encourage our participants to educate themselves on the history of the land we will be running on as well as the history of the land where you train and call home.

USATF Mountain/Ultra/Trail Running Youth Initiative:


To raise awareness of trail races among young runners and increase participation, the American Trail Running Association has partnered with the USATF MUT Youth Initiative to create a “Youth Trail” certified program for race directors. The TARC Blue Hills Skyline Trail Run is one of the early adopters of their program, and we offer discounted entries ($10 off) for youth 19 years old or under.


Please reach out if you are looking to register yourself or someone else through this program.

Trail Sisters Approved Event:


The TARC Blue Hills Skyline Trail Run 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 porta 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.

Adaptive Athletes:

We welcome the participation of adaptive athletes at our event!

  • Adaptive athletes must be able to run the course.

  • Tethers and guides may be used for athletes with a visual impairment.

  • Leg prosthetics may be used for amputees.

  • Crutches, braces, or poles may be used if indicated/necessary, with approval from the Race Director.

  • Please reach out with any questions or to let us know how we can best support you and your race day needs.

  • Guides for adaptive athletes can register as participants if they want their own time/result.

Volunteer Opportunities:

We need volunteers to help make this special day happen and to give our participants the experience they deserve! This includes help with bib pickup, course directing, aid stations, course sweeping, start/finish area support, parking guidance, etc. Volunteers are what make TARC events so fun and also run so smoothly. No experience is required, and it can be your first time attending one of our events! If you are bringing along family or friends to spectate, we encourage them to also get involved by volunteering. If you are running one of the shorter races, consider hanging around to help out afterward. Even if you can't make it on the day of the race, there are still opportunities to get involved. If you need service requirements for other races, we can also sign off on your hours! If we get enough folks, too, it's never a problem for our volunteers to become "course marshalls" and get some running in on the trails. All we ask is you help fill up some water bottles and tell runners they look awesome.

Please reach out if you or your organization are interested in volunteering. We welcome running clubs, hiking groups, sports teams, local businesses, and more to join us.

Registration for the various shifts will open around two months before the race date, but feel free to email us beforehand if you or your group is interested in volunteering.

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.

Parking & Travel:

Parking is available for participants right at the start/finish area in the parking lot of the Blue Hills Ski Area. Here is the address. Please help us out by carpooling with as many fellow trail animals as possible. Participants can post in the Trail Animals Running Club Facebook Group or in the TARC Blue Hills Skyline Trail Run event page coordinating carpools.

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!
