    About Colin's Joy Project:

    Colin McGrath was killed in 2018 after being struck by a car on his way home from a wonderful day in the park. His life was full of love, laughter, curiosity. Colin lived every minute of his life to the fullest. His laughing eyes, beautiful curls, hilarious voice, and sense of adventure will never be forgotten. His smile made everyone's heart happy.

    Since Colin's death, the McGrath family started a 501(c)(3) nonprofit organization called Colin's Joy Project. The mission of Colin's Joy Project is to enhance play spaces and sponsor children and family programming in the South Boston and surrounding communities.

    Colin's Joy Project has several active play space projects in development in South Boston inspired by Colin's Creativity Squad, an initiative that engages children in the community to design their own exciting, creative play spaces. Colin's Joy Project has also formed multiple community partnerships to which they have donated over $1.5M in the last 7 years! Through these partnerships, Colin's Joy Project fulfills their mission to bring joy to families the way Colin brought joy to all who knew him.

    A donation to Team Colin will support these long-lasting partnerships and future projects. Learn more about our work on our website www.colinsjoyproject.org, and follow us on Facebook and Instagram (@colinsjoyproject) for updates!

    The Esplanade Association (EA) invites YOU to enjoy a new season and new pace to support the same great cause! Rather than spring, we scheduled the annual 5K on Sunday, October 25—with hopes that a free parking day in the City of Boston amid fall foliage is a great opportunity to costume up and celebrate fitness and community in the park before Halloween!

    Building on the successful history of our beloved 5K Race, we are also introducing a dedicated Walk in succession to the annual Run. This staggered option will allow more individuals (including dog walkers, strollers and rollers!) to participate at their own pace and comfort level, while keeping pathway safety in mind as to not overcrowd the course. Please keep in mind: This is a shared-use, public pathway.

    There will be plenty to enjoy for 5K participants and fans alike, including fall-themed activities for the entire family, free samples from vendors, food, music, and more.

    Spots will fill up quickly, so don't miss out on the fun and sign up today!

    KNOW BEFORE YOU GO: ACCESSIBILITY

    We are committed to making the event as accessible and inclusive as possible. Here’s what to know about navigating the event space:

    • Entrances
    • The Frances Appleton Pedestrian Bridge at Charles Circle is the most accessible entry point to the park. There are two at-grade entrances to the park on either end of the park. One near the Museum of Science and Boston Police Barracks and the near the BU sailing pavilion.
    • Interior Footbridges
    • There are footbridges inside of the park that will be used as part of the race route that are constructed with cobblestone, creating an uneven surface. See example view of bridges. Please let us know if you anticipate this impacting your ability to participate.
    • Rideshare Drop-Off
    • If you’re looking to access the park via the Frances Appleton Footbridge, we recommend using 170 Charles Street (The Whitney Hotel) as your rideshare drop-off location.
    • Terrain:
    • The Esplanade has over five miles of paved pathways. Although they vary in width and smoothness, they are largely welcoming to all park visitors.
    • Restrooms:
    • There will be accessible gender-neutral portable restrooms on site.
    • Noise Level:
    • Expect occasional loud moments during the event, including music, speaker announcements, and cheering. These may affect guests who are sensitive to sound or rely on auditory cues for navigation. We encourage bringing noise-reducing gear if helpful.

    For additional accessibility questions or requests, please contact [email protected]

    EVENT FAQ

    What is the difference between the Run and the Walk?

    • The 5K Run is a timed event with separate start times and awards. The 5K Run is also family-friendly and we encourage all to participate that wish to do a more “competitive” (including competing against yourself) and fast-paced event. The Walk is untimed, family-friendly, and open to all—strollers and leashed dogs are welcome in the Walk only.

    Why did you change the format to include a "Walk" this year?

    • In an effort to be as inclusive as possible, and with the growing number of people interested, the decision was made to offer 2 distinct options. Pathway safety was also considered in this decision as the pathways can be narrow at times and crowded with both event participants and the general-use public. This update will mitigate overcrowding on the pathways, provide a space for all ability levels, and an option for everyone to come out and enjoy the event, all while ensuring a safe event.

    Can I walk in the 5K Run?

    • YES- walking is allowed in the 5K Run, but we ask that slower participants to start in the back (last wave). Please note: strollers and dogs are not permitted in the Run.

    Will restrooms be available on site?

    • YES- we will have portable restrooms available, including ADA Portable Restrooms, on site at Fiedler Field.

    Are there awards or prizes?

    • We will have awards/prizes for top finishers in their categories (see race categories) for the 5K Run ONLY. Participants in the 5K Run will be provided a chipped bib for timing. There are no awards for the 5K Walk.

    Will there be t-shirts?

    • NO- in an effort to reduce textile waste and continue to work towards a more sustainable and climate-friendly event, we will not be offering t-shirts. HOWEVER we will be offering a free, recycled and recyclable commemorative customized cup to registrants!

    Is there same-day registration?

    • YES- You may register the day of the event however we highly recommend pre-registration as historically this race has sold out. Registration will open at 8:00am. Please note that we can not guarantee a customized race bib if you register day-of and the cost of registration will be $45.00 for BOTH the Run and Walk.

    What if it rains?

    • The event is rain or shine! In cases of extreme weather, we’ll notify participants of any delays or cancellations via email, social media, and on our website.

    Can I get a refund if I am no longer able to make it?

    • Registrations are non-refundable, though you are able to transfer your registration. Please contact [email protected] if you have any questions. Your registration fee supports the Esplanade Association’s ability to care for the park, sustain it’s natural beauty, and provide free public programming for all!

    I am interested in volunteering, how do I sign up to volunteer?

    • ABSOLUTELY! We would love to have you as a volunteer. Please contact [email protected] if you would like more information.

    Is there parking on the Esplanade?

    • NO- There is not parking inside of the park. You can park in nearby garages or take advantage of the free metered street parking in Boston on Sundays.
