1K12M and the NKR

The National Kidney Registry is sponsoring the 1K12M (1 Kidney, 12 Marathons) challenge, in which kidney donor athletes Matt Cavanaugh and Hilary Baude will complete 12 marathons within one year—shattering the misperception that kidney donation imposes physical limits on donors. Along the way, they hope to raise awareness for the need for living kidney donors like themselves and motivate other athletes to consider donation.
