Tens of thousands of marathoners are raising money for children with disabilities and complex medical needs.

“It’s growing every year. It started off with just a couple of friends honoring a friend’s memory, who had passed away from cancer,” said marathoner Jon Bauer. “They started raising money for their local Children’s Miracle Network. Now we have locations all across the country, and the cool thing about is when we raise money locally, it stays to that Children’s Miracle Network. So locally we’re raising money for Gillette Children’s Specialty Healthcare.”
