When local attorney Mike Freed set out to jog nearly 160 miles across Florida in a week, he encountered his share of doubters. “You’re going to do what?

Freed, 48, erased those doubts Friday afternoon as he crossed the finish line on the lawn of the Duval County Courthouse, wrapping up the final leg of his six-day, six-marathon journey that took him from Tallahassee to Jacksonville.
