Campbell’s run was part of a fundraising effort in hope of finding a cure for the form of inflammatory bowel disease (IBD).

“I will tell you today, one of our team members is in Ryder Trauma where she’s been since late May and has had complication after complication. So I texted her yesterday that while I always run for Ricky, I am running for you Meagan,” said Campbell.

“I kept a nine minute mile pace,” said Anderson Dias.

For Dias the run was about faith and sacrifice.
