1K12M One Kidney, 12 Marathons

In 2023, NKR-sponsored kidney donor athletes Matt Cavanaugh and Hilary Baude will take on the 1K12M (One Kidney, 12 Marathons) challenge, completing 12 marathons within one year—shattering the misperception that kidney donation imposes physical limits on donors.

Along the way, they seek to raise awareness for the need for living kidney donors like themselves and hope to motivate individuals to consider donation.
