<p>The Chris Klug Foundation is a proud partner of Realbuzz and enjoys offering runners the opportunity to take on marathons and half marathons around the world. CKF runners have the opportunity to take on marathons such as the Berlin, Big Sur, and Miami marathons, among others. The Chris Klug Foundation uses the funds raised to make a difference and eliminate the wait for a transplant. Founded in October 2003 by Olympic Bronze Medalist and liver transplant recipient Chris Klug, CKF aims to promote lifesaving organ, eye, and tissue donation and work to improve the quality of life for those touched by transplantation. CKF uses the stories of organ donors, transplant candidates, and transplant recipients to inspire, alongside events, school courses, and webinars to educate. All with the end goal of encouraging individuals to give the gift of life and register as organ donors.</p>
