Sixteen-year-old Miles thought he was being called onstage to tell everyone about the wish he wanted, but had no idea that today, on his birthday, his wish would be granted.
Miles was diagnosed with sickle cell anemia when he was a baby. His mom said he spends several days in the hospital every so often due to overwhelming pain.
When approached by Make-A-Wish Mid-Atlantic to do or see anything he wanted, Miles wished to meet Lewis Hamilton, a racecar driver, and to see him race in Monaco.
Sunday morning at the 2018 Walk For Wishes, Miles was told that his wish would be granted next month.
His mom kissed him on the cheek while the crowd sang "Happy Birthday" to Miles.
The Walk For Wishes helps Make-A-Wish Mid-Atlantic raise money to grant wishes for kids like Miles, and the other 840 local children diagnosed with serious illnesses each year.
This year's Walk For Wishes coincided with World Wish Day, which celebrates the anniversary of the first wish ever granted. The organization is now in its 38th year of granting wishes.
They were also recognized by Guinness World Records and awarded the title of largest wish-granting organization.
