  The town of Boylston celebrates Memorial Day in style every year with events for the whole family. The common in Boylston is a beautiful location to enjoy the race and then spend time with your friends and family. There is no better location for Katie’s 5k!

  SHIRTS WILL ONLY BE GUARANTEED TO THOSE WHO REGISTER BY MAY 8TH.

  TEAM Information

  What's better then running alone? Running with friends! Be sure to create or join a team when you register this year. We will be awarding prizes to the Top 2 fastest teams (first 5 on a team to finish count toward the official the team time) as well as the team with the most number of participants!

  WHY DO WE RUN?

  Katie Chalifoux was born in October of 1984 to Janice and Robert Chalifoux. The youngest of five children, Katie spent her childhood in Boylston, surrounded by a closely-knit group of friends. At Tahanto Regional High School, Katie was not only a scholar, but she was also active in sports (soccer, basketball, and softball), music (clarinet and piano), and numerous extra-curricular activities (class officer, Model United Nations, and Student Council).

  Katie’s full life came to an unexpected and tragic end in January of 2008, after she succumbed to complications following an accident in New York City. At the time of her death, Katie was working as a teacher at Wild Blue, an enrichment program for children on the upper east side of Manhattan. She loved life and was living out her dream of living in New York City. She was the epitome of “living life to the fullest”.

  In 2008, the Boylston Memorial Day 5K race was renamed and reworked in Katie’s memory. Scholarships in Katie's name were setup for deserving female students from Tahanto Regional High School who were going on to a two or four year college degree program. The race also honors our veterans with donations to Veterans Inc. in Worcester.

  In 2018, the Boylston Lions Club took stewardship of Katie's 5K and will work to continue the high quality race it has been in the past. The race now supports the Katie Chalifoux Scholarships, The Boylston Lions Club Scholarships, and donations to Veterans, Inc.

  The 2026 Unified 5k and AdaptXpo is an inclusive road race and adaptive sports expo designed so that everyone can participate, whether they run, walk, row, or roll. The event raises critical funds for AdaptX education, research, community events, fitness programming, and grant initiatives. The Unified 5k is a space where athletes with and without disabilities show up together, challenge perceptions, and prove that fitness and sport are more meaningful when everyone has a place at the starting line.

  Join us on May 30th at RFK Community Alliance for our 8th annual event where you can walk, run, roll, or row either the 5k (3.1 mile) or 1 mile course. Arrive early or hang around after the event to check out our vendors and clinics at the AdaptXpo, a celebration of organizations that focus on health, inclusion, accessibility, assistive technology, and adaptive sports.

  Help us make fitness and physical activity accessible for every body.

  2026 Bare Hill Races

  NEW THIS YEAR: The TRI is a USAT SCORING EVENT for the MA STATE CHAMPIONSHIPS!

  2026 USA Triathlon State Championship Pilot Program Overview and Eligibility Requirements

  This is a 2026 USA Triathlon State Championships Ranking Point Event (triathlon races of any distance are eligible) which is a part of the USA Triathlon State Championship Pilot Program debuting in Florida and Massachusetts. Every USA Triathlon-sanctioned triathlon race within the state is a part of this program.The program leverages USAT’s existing rankings system for seamless point tabulation and encourages athletes to race local. This creates process simplicity, efficiency, and allows for a clear, data-driven recognition of the state’s most competitive multisport athletes. In order to be eligible to be crowned a State Champion, the requirements are listed below:

  • Athletes must complete at least three USAT-sanctioned races (any distance triathlon) in Massachusetts

  • In order to be crowned a State Champion, the athlete’s membership address must be in Massachusetts

  • For example, someone that meets the three-race threshold in Massachusetts but does not have a Massachusetts USAT Membership address will not be eligible to win a Massachusetts State Championship.

  At the end of the season, an athlete’s total USAT rankings points (from all triathlon races, regardless of location) will determine the State Champion in each age group—provided the athlete has met the in-state triathlon race minimum. Champions will then be crowned and communication will be distributed from USA Triathlon recognized those athletes.

  LOCATION: 4 Pond Road, Harvard, MA, 01451

  We are excited to announce that the Bare Hill Races will take place on Sunday, June 7th, 2026 in our charming town of Harvard, MA. This grassroots race is perfectly suited for the new to multi-sport athletes all the way up to the seasoned athletes vying to qualify for National Championship slots.

  • We HIGHLY recommend that you use the online registration and credit card payment option (even if you plan to sign up in-person).

  • This will make things faster and smoother on race day morning.

  • You can register in-person (4 Pond Road, Harvard, MA) on Saturday, June 6th between 4PM-6PM or Sunday, June 7th between 6:30AM-7:30AM.
