Lots of 10-year-olds spend their days playing fortnite, on their iphones or playing after school sports but a young hero by the name of Niall McDermott spent his past 50 days running 5k Marathons.
Sunday at Crissy Field in SF, Niall completed his 50th 5-kilometer run in 50 days.
By running all these races Niall raised more than $4,000 for lung cancer research. He was inspired to do this because his grandpa is fighting with Lung cancer right now in Maryland.
