In 2006, Gilbert and a group of runners interested in helping others established the Gazelle Foundation, a 501(c)(3) charitable foundation with a mission to fund and build clean-water projects in Burundi, Africa. One of the poorest countries on earth, most people in rural Burundi walk over two miles for untreated water from streams and puddles, often shared with livestock. Illness from waterborne infections is high, and a major factor in limiting access to education and economic stability. Through clean water projects, the Gazelle Foundation is offering a first step in breaking the vicious cycle of poverty in Burundi. As of January 2018, the Gazelle Foundation has provided access to clean water to more than 84,000 Burundi citizens.
Locally, in Gilbert’s hometown of Austin, Texas, the Gazelle Foundation empowers Central Texas youth through water education programs and activities.
