3 running, duathlon, and walking events in East Islip, New York

Run the scenic perimeter of Heckscher State Park in the Heckscher Classic! Choose between a 7-mile or 14-mile course on smooth, runnable trails. Perfect for both new trail runners and experienced athletes.

The course follows the perimeter of Heckscher State Park in a clockwise direction and will be clearly marked.

This event is one step up from a fat ass–style run. Timing will be done by hand, and a basic aid station with water and light snacks will be available at the start/finish area (mile 7).

Each participant will receive a finisher’s medal, and awards will be given to the top three male and female finishers in each distance. Participants will also receive a Heckscher Classic Bucket Hat!

Participants in the King of the Hill 3-Hour Run on March 7th at Sunken Meadow State Park will receive $10 off race registration.

Join Chasing the Rainbows this Bereaved Mother’s Day weekend for the Busting Bubble 5K Walk & Run, a heartfelt event dedicated to healing, remembrance, and community. Whether you join us in person at one of our many locations or participate virtually, your involvement helps raise awareness and provides vital support for families grieving infertility, pregnancy loss, stillbirth, or infant loss.

Why Bubbles?

Bubbles symbolize the many shapes and moments of grief, unexpected, unique, and deeply personal. Just as bubbles reflect rainbows in the light, they remind us of the signs, love, and connections our babies continue to send. These brief glimmers of color reflect the memories that stay with us forever.

Our Purpose

To raise awareness and offer essential support to families grieving the unimaginable.

Your Impact: Supporting 11 Daily, Free, Trauma Informed Services

By registering, you directly support Chasing the Rainbows’ 11 free services that offer daily, compassionate care. These include virtual support groups held four times a day for a total of eighteen sessions each week, in-person support groups throughout the United States, peer mentors, trauma therapy, the Cry It Out Loud podcast, coping care packages, mindful movement, online private chat communities, resources for family members, perinatal bereavement training for medical units, and community events. These programs ensure that no one has to navigate grief alone.

A Celebration of Life

This event is more than a walk or run. It is a joyful and healing gathering filled with live entertainment, vendors, and sponsors. Together, we will celebrate the lives of the little ones we carry in our hearts and the strength of those who love them.

The Wall to Remember

We will feature a Wall to Remember, a touching tribute honoring babies gone too soon. It offers a space for reflection, connection, and remembrance.
