Ethan Lam and Kim Chan

For the past two years, Kim Chan, 44, of Huntington Beach, California, has run the Long Beach half-marathon in honor of her grandfather, who died from Alzheimer’s disease. This year, Kim’s 11-year-old son, Ethan Lam, ran along with her, beating her time by 20 minutes. “He came in third in his age group and raised more than $1,000 for Cure Alzheimer’s Fund,” said Kim. “I’m so proud that he was able to achieve a challenging personal goal and fundraise for a worthy cause.”
