We all know that the hunky singer’s brother Adam has been battling brain cancer for over a decade and he has been very supportive of him. And now, David Cook will run for him on May 3 in Washington, D.C.
According to reports, he will serve as grand marshal in the “Race for Hope 5K” which benefits brain cancer research. David Cook will also join the race as part of a team he set up – which has already raised more than $40,000. Race co-chair Jeff Kolodin told PEOPLE:

“He wants nothing from us at all. This transcends fame and money and everything else. He just wants to help the cause.”

David Cook, meanwhile, says: “The opportunity to become involved in such a worthwhile cause is paramount for me and my family. I don’t run normally, but it seems a small sacrifice compared to what those who have fought cancer have endured. And the fact that my fans have rallied to raise so much in donations is the biggest compliment.” Atta boy! Your blessings today are so well-deserve coz you have such a good heart! =)
