The Liver Life Walk Phoenix Presented by Mayo Clinic, is celebrating the 16th Anniversary of our dog friendly fundraising walk. Nearly 750 walkers will be pounding the pavement for this 5k/1k walk that is fun for all ages. Individual walkers and team walkers are encouraged to register. All walkers that raise $100 or more will receive the National Walk Shirt to commemorate the day. There is a $20 registration fee and all proceeds go to help the American Liver Foundation provide critical research funding, public education, and patient support. Walkers 17 and under are free.
