Coming April 19, 2015. Okay TrailblazerGirls, here’s a chance to get out and support an event that started in 2013 as a way to celebrate the 40th anniversary of Title IX! The Gazelle Girl Half Marathon and 5K is Michigan’s first womenÂ-only half marathon and continues the tradition of supporting women in athletics by raising funds for several community based charities that are dedicated to empowering women of all ages. This urban marathon and 5K will be timed and take you through the streets of downtown Grand Rapids along the banks of the Grand River. It will be a bit nippy out, so dress accordingly and feel the camaraderie with other women who are endorsing health and fitness.
