Description

Join us on Saturday, May 16 for our 8th annual Trillium Spring 5K!

We’re proud to be partnering with Girls on the Run Greater Boston (GOTRGB) and bringing together a global community for our most exciting race to date. With over 500 in person runners and hundreds of virtual participants, we invite you all to join us in supporting an incredibly important cause.

About Girls on the Run Greater Boston (GOTRGB)

Girls on the Run Greater Boston (GOTRGB) is a positive youth development program that inspires girls in grades 3-8 to be joyful, healthy and confident through an experience-based curriculum that
creatively integrates running and physical activity. Since 2010, GOTRGB has empowered more than 22,000 girls to recognize and activate their limitless potential, giving them the confidence to boldly pursue their dreams.

Each season, coaches help girls build a toolbox of social-emotional skills like standing up for
themselves and others, managing emotions, and intentionally choosing friends. Each lesson
covers a topic through interactive games, discussions and physical activities. Over the course of
the program the girls work on goal setting with their sights set on a season-ending Celebratory
5K, where they move at their “happy pace” to complete the 5K.
