We are turning 20 this year, and we thought we would have a little birthday fun with all of you! This challenge will occur over CKF's birth week from Sunday, October 22nd, to Saturday, October 28th! All are welcome to take part in this virtual challenge. The aim of the game is to be active for twenty; whether that is minutes, hours, miles, or laps, it is up to you. Register here to join the challenge, then on the week of the 22nd, join us as we show the world what organ donation means to the transplant community. We ask you to post a photo of yourself taking on the challenge and #CKFBirthdayChallenge, and every participant will receive a sweet CKF Birthday challenge shirt!
