The United Way of Chatham-Kent and Greenfield Energy will combine to raise money for a good cause.
It's the fifth annual Harvest Run this morning.
The United Way's Tom Slager says it's all about having fun and supporting local agencies at the same time.
"It's really pushed by Greenfield Energy and they've been a huge backer for this," says Slager. "It's a fundraiser that they do and it does support United Way programs."
The event raised $20,000 last year.
The half marathon goes at 9am from McGregor Secondary School in Chatham, while the other distances get underway closer to 10am.
