Mark your calendars for Saturday, September 13, and head to Lions Park for an epic day of racing and community celebration. And don't forget about the post-race party – it's going to be a blast! This is an event you won't want to miss, so join us for an unforgettable day of fitness, fun, and togetherness!

Join us in supporting GSNI's financial assistance programs. We're on a mission to ensure that every girl has the opportunity to experience the amazing world of Girl Scouts, no matter what challenges they face. From membership fees to uniforms, books, and even international adventures, we're dedicated to making the Girl Scout journey accessible to all. Last year, we raised an incredible $13,000 thanks to our phenomenal supporters, enabling us to continue shaping girls into courageous, confident, and compassionate leaders. Are you fired up to help us surpass that achievement this year? Let's go above and beyond!
