WAKEFIELD (CBS) – Sean Devan prepared Friday night for a 12 hour run.

He joined hundreds of other runners in Wakefield as they do several three-mile laps around scenic Lake Quannapowitt, but Sean’s not just running for physical fitness, he’s doing it for charity, benefiting Lazarus House, a local ministry in Lawrence serving the poor.

WBZ-TV’s Jim Smith reports

Sean planned to cover about 70 miles over the 12 hours.

With every step, he’ll be thinking about the people he’s helping.

Sean has run five marathons and completed one 50 mile run, but this he says will be even tougher.
