Lucas Isaacs of Bonner Spring, Kan., dominated the Out-Pace USRA B-Mod main event on the final night of the Iron Man Challenge during King of America VI presented by Chix Gear at the Humboldt Speedway. After the race's first and only caution early on, Isaacs continually pulled away from the field to take a decisive full straight-away win and collect the $1,000 top prize.
